I literally have tens of thousands of dollars in top-shelf hardware, looking to repurpose some before selling on eBay to build a NAS system, possibly a dedicated firewall device as well. o_O
Q1) What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.** A1) This will be a dedicated NAS system for my home network. As such, I'm looking to have it: - Host ##TB's of 720, 1080 & up resolution Movies and TV Shows I'm about to begin ripping from a MASSIVE DVD & Blueray collection I have. - My kids are big on Minecraft. I understand it's possible to host your own "worlds" (or whatever they call the maps you can build) on your own "server". I think it would be pretty neat to offer them (& their friends - if can be done 'safely/securely') their own partition on one of my NAS HDD's. - I also have accounts with a couple diff VPN companies... I understand it's possible (?) to sync said VPN's with a NAS, this might be a more relative topic on the next point/purpose... - I'd like to be able to remotely link to this NAS for when I travel overseas and want to stream at my temp location from my house/this NAS. ______________________ Q2) What is your maximum budget before rebates/shipping/taxes?** * A2) Here's where I make matters more complicated than most others would... I've been an advocate for Bitcoin and crypto-currencies in general since 2013. I invested in a small mining outfit back in 2014 (strictly Bitcoin/ASIC's). One of my buddies is the President of a large-scale mining operation (foreign and domestic) and he convinced me to dabble in the GPU mining-space. I made my first hardware purchase in Q4, 2017 and launched a small-scale GPU-Farm in my house since then. I had the rigs mining up until Q3 of 2018 (not cost-efficient to keep on, especially living in SoFlo) and since then, the hardware's been collecting dust (& pissing off my family members since they lost access to 3X rooms in the house - I won't let anyone go near my gear). One of my New Years Resolutions for 2019 was to clear out the house of all my mining equipment so that's all about to go up on eBay. So "budget" is relative to whatever I "MUST" spend if I can't repurpose any of the parts I already have on hand for this build... (Anyone having something I "need" and is looking to barter for one of the items I'll list later on in here, LMK). ______________________ Q3) When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.** A3) IMMEDIATELY! :) ______________________ Q4) What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc\)** A4) Well I had a half-assed idea approximately 1 year ago that it might be wise to build a bunch of 'gaming rigs' to sell on eBay with my intended repurposed mining hardware so I went on a shopping spree for like 6 months. That said; I've got a plethora of various other components that aren't even unboxed yet. 90% of the items I've purchased for this additional project were items that were marked down via MIR (mail-in-rebates) & what-not...
AFAIK, there are only 3X items I absolutely do not have which I 'MUST' find. Those would be - 1) Motherboard which accepts "ECC RAM". 2) CPU for said MOBO. 3) Said "ECC RAM".\*
______________________ Q5) Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?** A5) I'm located in Southwest Florida. No Microcenter's here. Best Buy is pretty much my only option although I am a member of Newegg, Amazon & Costco if that makes any difference? ______________________ Q6) If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.** A6) In an attempt to better clean up this Q&A, I'm going to list the items I have on-hand at the end of this questionnaire in-case passers-by feel like this might be a TLDR.* (Scroll to the bottom & you'll see what I mean). ______________________ Q7) Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?** A7) I don't think that's necessary for my intended purpose although - I'm not against it if that helps & FWIW, I'm pretty skilled @ this task already (it's not rocket science). ______________________ Q8) Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)** A8) As stated in A4; ECC RAM is non-negotiable... RAID seems like a logical application here as well. - This will predominantly be receiving commands from MacOS computers. I don't think that matters really but figured it couldn't hurt to let you guys know.\* - I'd also be quite fond of implementing "PFSENSE" (or something of that caliber) applied to this system so I could give my Netgear Nighthawks less stress in that arena, plus my limited understanding of PFSENSE is that it's ability to act as a firewall runs circles around anything that comes with consumer-grade Wi-Fi routers (like my Nighthawks). Just the same, I'm open to building a second rig just for the firewall.\* - Another desirable feature would be that it draws as little electricity from the wall as possible. (I'm EXTREMELY skilled in this arena. I have "Kill-A-Watts" to test/gauge on, as well as an intimate understanding of the differences between Silver, Gold, Platinum and Titanium rated PSU's. As well as having already measured each of the PSU's I have on-hand and taken note of the 'target TDP draw' ("Peak Power Efficiency Draw") each one offers when primed with X amount of GPU's when I used them for their original purpose.\* - Last, but not least, sound (as in noise created from the rig). I'd like to prop this device up on my entertainment center in the living room. I've (almost) all of the top-shelf consumer grade products one could dream of regarding fans and other thermal-related artifacts. - Almost forgot; this will be hosting to devices on the KODI platform (unless you guys have better alternative suggestions?) ______________________ Q9) Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?** A9) Definitely! Desired theme would be WHITE. If that doesn't work for whatever reason, black or gray would suffice. Regarding "Case Size". Nah, that's not too important although I don't foresee a mini-ITX build making sense if I'm going to be cramming double digit amounts of TB in the system, Internal HDD's sounds better than a bunch of externals plugged in all the USB ports. ______________________ Q10) Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?** A10) I don't know. If I do need a copy of Windows, I don't have one so that's something I'll have to consider I guess. I doubt that's a necessity though. ______________________ ______________________ ______________________ **Extra info or particulars:*\* AND NOW TO THE FUN-STUFF... Here's a list of everything (PARTS PARTS PARTS) I have on-hand and ready to deploy into the wild &/or negotiate a trade/barter with: CASES - Corsair Carbide Series Air 540 Arctic White (Model# Crypto-Currency-9011048-WW) - (Probably my top pick for this build).

At which time I'd be obliged to send an itemized list or see if I have what they're/you're specifically looking for.\* ______________________ THERMAL APPLICATIONS/FANS - JUST FANS - BeQuiet - Pure Wings 2 (80mm) Pure Wings 2 (120mm) Pure Wings 2 (140mm) Silent Wings 3 PWM (120mm) NOCTUA - PoopBrown - NF-A20 PWM (200mm) Specifically for the BIG "CoolerMaster HAF XB EVO" Case GREY - NF-P12 Redux - 1700RPM (120mm) PWM Corsair - Air Series AF120LED (120mm) CPU COOLING SYSTEMS - NOCTUA - NT-HH 1.4ml Thermal Compound NH-D15 6 Heatpipe system (this thing is the tits) EVGA (Extremely crappy coding in the software here, I'm like 99.99% these will be problematic if I were to try and use in any OS outside of Windows, because they barely ever work in the intended Windows as it is). CLC 240 (240mm Water-cooled system CRYORIG - Cryorig C7 Cu (Low-Profile Copper Edition*) A few other oversized CPU cooling systems I forget off the top of my head but a CPU cooler is a CPU cooler after comparing to the previous 3 models I mentioned. I almost exclusively am using these amazing "Innovation Cooling Graphite Thermal Pads" as an alternative to thermal paste for my CPU's. They're not cheap but they literally last forever. NZXT - Sentry Mesh Fan Controller ______________________ POWER SUPPLIES (PSU's) - BeQuiet 550W Straight Power 11 (GOLD) EVGA - 750P2 (750W, Platinum) 850P2 (850W, Platinum) 750T2 (750W, TITANIUM - yeah baby, yeah) ROSEWILL - Quark 750W Platinum Quark 650W Platinum SEASONIC - Focus 750W Platinum ______________________ STORAGE - HGST Ultrastar 3TB - 64mb Cache - 7200RPM Sata III (3.5) 4X Samsung 860 EVO 500GB SSD's 2X Team Group L5 LITE 3D 2.5" SSD's 480GB 2X WD 10TB Essential EXT (I'm cool with shucking) + 6X various other external HDD's (from 4-8TB) - (Seagate, WD & G-Drives) ______________________ Other accessories worth mentioning - PCI-E to 4X USB hub-adapter (I have a dozen or so of these - might not be sufficient enough &/or needed but again, 'worth mentioning' in case I somehow ever run out of SATA & USB ports and have extra external USB HDD's. Although, I'm sure there would be better suited components if I get to that point that probably won't cost all that much). ______________________ ______________________ ______________________ Needless to say, I have at least 1X of everything mentioned above. In most all cases, I have multiples of these items but obviously won't be needing 2X CPU's, Cases, etc... Naturally, I have GPU's. Specifically; At least 1X of every. Single. NVIDIA GTX 1070 TI (Yes, I have every variation of the 1070 ti made by MSI, EVGA and Zotac. The only brand I don't have is the Gigabyte line. My partners have terrible experience with those so I didn't even bother. I'm clearly not going to be needing a GPU for this build but again, I'm cool with discussing the idea of a barter if anyone reading this is in the market for one. I also have some GTX 1080 TI's but those are already spoken for, sorry. It's my understanding that select CPU's I have on this list are ECC Friendly and AFAIK, only 1 of my MOBO's claims to be ECC Friendly (The ASROCK AB350M PRO4), but for the life of me, I can't find any corresponding forums that confirm this and/or direct me to a listing where I can buy compatible RAM. Just the same, if I go w/ the ASROCK MOBO, that means I'd be using one of the Ryzens. Those are DEF. power hungry little buggers. Not a deal-breaker, just hoping to find something a little more conservative in terms of TDP. In closing, I don't really need someone to hold my hand with the build part as much as figuring out which motherboard, CPU and RAM to get. Then I'm DEFINITELY going to need some guidance on what OS is best for my desired purpose. If building 2X Rigs makes sense, I'm totally open to that as well... Rig 1 = EPIC NAS SYSTEM Rig 2 = EPIC PFSENSE (or the like) DEDICATED FIREWALL Oh, I almost forgot... The current routers I'm using are... 1X Netgear Nighthawk 6900P (Modem + Router) 1X Netgear Nighthawk X6S (AC 4000 I believe - Router dedicated towards my personal devices - no IoT &/or Guests allowed on this one) 1X TP-Link Archer C5 (Router). Total overkill after implementing the Nighthawks but this old beast somehow has the best range, plus it has 2X USB ports so for now, it's dedicated towards my IoT devices. ---- I also have a few other Wi-Fi routers (Apple Airport Extreme & some inferior Netgear's but I can only allocate so many WiFi Routers to so many WiFi channels w/out pissing off my neighbors) On that note, I have managed to convince my neighbors to let me in their house/WiFi configuration so we all have our hardware locked on specific, non-competing frequencies/channels so everyone's happy. :) Please spare me the insults as I insulted myself throughout this entire venture. Part of why I did this was because when I was a kid, I used to fantasize about building a 'DREAM PC' but could never afford such. To compensate for this deficiency, I would actually print out the latest and greatest hardware components on a word document, print the lists up & tape to wall (for motivation). I was C++ certified at the age of 14 and built my first PC when I was 7. At the age of 15 I abandoned all hope in the sector and moved on to other aspirations. This entire ordeal was largely based off me finally fulfilling a childhood fantasy. On that note = mission accomplished. Now if I'm actually able to fulfill my desires on this post, I'm definitely going to feel less shitty about blowing so much money on all this stuff over the last couple years. TIA for assisting in any way possible. Gotta love the internets! THE END. :) EDIT/UPDATE (5 hours after OP) - My inbox is being inundated with various people asking for prices and other reasonable questions about my hardware being up for sale. Not to be redundant but rather to expound on my previous remarks about 'being interested in a bartetrade' with any of you here... I did say I was going to sell my gear on eBay in the near future, I also said I wanted to trade/barter for anything relative to helping me accomplish my OP's mission(s). I'm not desperate for the $$$ but I'm also not one of those people that likes to rip other people off. That said; I value my time and money invested in this hardware and I'm only willing to unload it all once I've established I have ZERO need for any of it here in my home first. Hence my writing this lengthy thread in an attempt to repurpose at least a grand or two I've already spent. One of the most commonly asked questions I anticipate receiving from interested bodies is going to be "How hard were you on your hardware?" Contrary to what anyone else would have probably done in my scenario which is say they were light on it whether they were or weren't, I documented my handling of the hardware, and have no problem sharing such documentation with verified, interested buyers (WHEN THE TIME COMES) to offer you guys peace of mind. I have photo's and video's of the venture from A-Z. I am also obliged to provide (redacted) electricity bill statements where you can correlate my photo's (power draw on each rig), and also accurately deduct the excess power my house consumed with our other household appliances. Even taking into consideration how much (more) I spent in electricity from keeping my house at a constant, cool 70-72F year-round (via my Nest thermostat). Even without the rigs, I keep my AC @ 70 when I'm home and for the last 1.5-2 years, I just so happened to spend 85% of my time here at my house. When I would travel, I'd keep it at 72 for my wife & kids. Additionally; I had each GPU 'custom' oveunderclocke'd (MSI Afterburner for all GPU's but the EVGA's).* I doubt everyone reading this is aware so this is for those that don't.... EVGA had the brilliant idea of implementing what they call "ICX technology" in their latest NVIDIA GTX GPU's. The short(est) explanation of this "feature" goes as follows: EVGA GPU's w/ "ICX 9 & above" have EXTRA HEAT/THERMAL SENSORS. Unlike every other GTX 1070 ti on the market, the one's with this feature actually have each of 2/2 on-board fans connected to individual thermal sensors. Which means - if you were to use the MSI Afterburner program on one of these EVGA's and create a custom fan curve for it, you'd only be able to get 1/2 of the fans to function the way intended. The other fan simply would not engage as the MSI Afterburner software wasn't designed/coded to recognize/ communicate with an added sensor (let alone sensor'S). This, in-turn, would likely result in whoever's using it the unintended way having a GPU defect on them within the first few months I'd imagine... Perhaps if they had the TDP power settings dumbed down as much as I did (60-63%), they might get a year or two out of it since it wouldn't run as near as hot, but I doubt any longer than that since cutting off 50% of the cooling system on one of these can't be ignored too long, surely capacitors would start to blow and who knows what else... (Warning = RANT) Another interesting side-note about the EVGA's and their "Precision-X" OveUnderclocking software is that it's designed to only recognize 4X GPU's on a single system. For miners, that's just not cool. My favorite builds had 8X and for the motherboards that weren't capable of maintaining stable sessions on 8, I set up with 6X. Only my EVGA Rigs had 3 or 4X GPU's dedicated to a single motherboard. Furthermore, and as stated in an earlier paragraph, (& this is just my opinion) = EVGA SOFTWARE SUCKS! Precision X wasn't friendly with every motherboard/CPU I threw at it and their extension software for the CLC Close-Loop-Cooling/ CPU water-coolers simply didn't work on anything, even integrating into their own Precision-X software. The amount of time it took me to finally find compatible matches with that stuff was beyond maddening. (END RANT). Which leads me to my other comments on the matter. That's what I had every single 1070 ti set at for TDP = 60-63%. Dropping the power load that much allowed me to bring down (on average) each 1070 ti to a constant 110-115W (mind you, this is only possible w/ "Titanium" rated PSU's, Platinum comes pretty damn close to the Titanium though) while mining Ethereum and was still able to maintain a bottom of 30 MH/s and a ceiling of 32 MH/s. Increasing the TDP to 80, 90, 100% or more only increased my hashrates (yields) negligibly, like 35-36 MH/s TOPS, which also meant each one was not only pulling 160-180W+ (Vs. the aforementioned 115'ish range), it also meant my rigs were creating a significantly greater amount of heat! Fortunately for the GPU's and my own personal habits, I live in South Florida where it's hot as balls typically, last winter was nothing like this one. Increasing my yields by 10-15% didn't justify increasing the heat production in my house by >30%, nor the added electricity costs from subjecting my AC handlers to that much of an extra work-load. For anyone reading this that doesn't know/understand what I'm talking about - after spending no less than 2-3 hours with each. and. every. one. I didn't play with the settings on just one and universally apply the settings to the rest. I found the 'prime' settings and documented them with a label-maker and notepad. Here's the math in a more transparent manner: *** I NEVER LET MY GPU's BREACH 61C, EVER. Only my 8X GPU rigs saw 60-61 & it was the ones I had in the center of the build (naturally). I have REALLY high power fans (used on BTC ASIC MINERS) that were sucking air from those GPU's which was the only way I was able to obtain such stellar results while mining with them. **\* Mining at "acceptable" heat temps (not acceptable to me, but most of the internet would disagree = 70C) and overclocking accordingly brings in X amount of yields per unit. = 'Tweaking' (underclocking) the GPU's to my parameters reduced my yield per unit from -10-15%, but it SAVED me well over 30-35% in direct electricity consumption, and an unknown amount of passive electricity consumption via creating approximately 20%+ less heat for my AC handler to combat. I say all this extra stuff not just for anyone interested in mining with their GPU's, but really to answer (in-depth) the apparent questions you people are asking me in PM's. Something else that should help justify my claims of being so conservative should be the fact I only have/used "Platinum and Titanium" rated PSU's. Heat production, power efficiency and longevity of the hardware were ALWAYS my top priority.* . I truly thought Crypto would continue to gain and/or recover and bounce back faster than it did. If this project had maintained positive income for 12 months+, I'd have expanded one of our sites to also cater to GPU mining on a gnarly scale. Once I have my NAS (& possibly 2nd rig for the firewall) successfully built, I'll be willing/able to entertain selling you guys some/all of the remaining hardware prior to launching on eBay. If there's something you're specifically looking for that I listed having, feel free to PM me with that/those specific item(s). Don't count on an immediate response but what you can count on is me honoring my word in offering whoever asks first right of refusal when the time comes for me to sell this stuff. Fortunately for me, PM's are time-stamped so that's how I'll gauge everyone's place in line. I hope this extra edit answers most of the questions you guys wanted to have answered and if not, sorry I guess. I'll do my best to bring light to anything I've missed out on after I realize whatever that error was/is. The only way anyone is getting first dibs on my hardware otherwise is if they either offer compelling insight into my original questions, or have something I need to trade w/. THE END (Round#2)
New people please read this. [upvote for visibility please]
I am seeing too many new people come and and getting confused. Litecoin wiki isn't the greatest when it comes to summing up things so I will try to do things as best as I can. I will attempt to explain from what I have learned and answer some questions. Hopefully people smarter than me will also chime in. I will keep this post updated as much as I can. Preface Litecoin is a type to electronic currency. It is just like Bitcoin but it there are differences. Difference explained here. If you are starting to mine now chances are that you have missed the Bitcoin mining train. If you really want your time and processing power to not go to waste you should mine LTC because the access to BTC from there is much easier. Mining. What is it? Let's get this straight. When making any financial commitment to this be prepared to do it with "throw away" money. Mining is all about the hashrate and is measured in KH/s (KiloHash/sec). Unlike the powerful ASICs (Application Specific Integrated Circuit) that are used to mine bitcoins using hashrates in the GH/s and even TH/s, litecoin mining has only been able to achieve at the very best MH/s. I think the highest I've seen is 130 MH/s so far. Which leads us to our next section. Mining Hardware While CPU mining is still a thing it is not as powerful as GPU mining. Your laptop might be able to get 1 a month. However, I encourage you to consult this list first. List of hardware comparison You will find the highest of processors can maybe pull 100 KH/s and if we put this into a litecoin mining calculator it doesn't give us much. Another reason why you don't want to mine with your CPU is pretty simple. You are going to destroy it. So this leaves us with GPUs. Over the past few months (and years) the HD 7950 has been the favourite because it drains less power and has a pretty good hashrate. But recently the introduction of the R9 290 (not the x) has changed the game a bit. People are getting 850 KH/s - 900 KH/s with that card. It's crazy. Should I mine? Honestly given the current difficulty you can make a solid rig for about $1100 with a hashrate of 1700 KH/s which would give you your investment back in about a month and a half. I am sure people out there can create something for much cheaper. Here is a good example of a setup as suggested by dystopiats PCPartPicker part list / Price breakdown by merchant / Benchmarks

Estimated Hashrate (with GPU overclocking) : 1900 KH/s Hardware Fundamentals CPU - Do you need a powerful CPU? No but make sure it is a decent one. AMD CPUs are cheap to buy right now with tons of power. Feel free to use a Sempron or Celeron depending on what Motherboard you go with. RAM - Try to get at least 4 GB so as to not run into any trouble. Memory is cheap these days. I am saying 4 GB only because of Windoze. If you are plan to run this on Linux you can even get away with less memory. HDD Any good ol 7200 RPM hard drive will do. Make sure it is appropriate. No point in buying a 1TB hard drive. Since, this is a newbie's guide I assumed most won't know how to run linux, but incase you do you can get a USB flash drive and run linux from it thus removing the need for hard drive all toghether. (thanks dystopiats) GPU - Consult the list of hardware of hardware I posted above. Make sure you consider the KH/s/W ratio. To me the 290 is the best option but you can skimp down to 7950 if you like. PSU - THIS IS BLOODY IMPORTANT. Most modern GPUs are power hungry so please make sure you are well within the limits of your power consumption. MOTHERBOARD - Ok, so a pretty popular board right now is Gigabyte GA-990FXA-UD3 and the ASRock 970 Extreme4. Some people are even going for Gigabyte GA-990FXA-UD5 and even the mighty Gigabyte GA-990FXA-UD7 because it has more PCI-E slots. 6 to be exact. However you may not need that much. With risers you can get more shoved into less. PCI-E RISERS - These are called risers. They come in x16 to x16 and x1 to x16 connections. Here is the general rule of thumb. This is very important. Always get a POWERED riser otherwise you will burn a hole in your MoBo. A powered rise as a molex connector so that additional power from PSU can be supplied. When it comes to hardware I've provided the most basic knowledge you need. Also, take a look at cryptobader's website. This is very helpful. Please visit the mining section of Litecoin Forums and the litecoinmining subreddit for more indepth info. Mining Software Now that you have assembled your hardware now you need to get into a pool. But before you do that you need a mining software. There are many different ones but the one that is most popular is cgminer. Download it and make sure you read the README. It is a very robust piece of software. Please read this if you want to know more. (thanks BalzOnYer4Head) Mining Pools Now that your hardware and software is ready. I know nothing about solo mining other than the fact that you have to be very lucky and respectable amount of hashing power to decrypt a block. So it is better to join pools. I have been pool hopping for a bit and really liked give-me-coin previously known to the community as give-me-ltc. They have a nice mobile app and 0% pool fees. This is really a personal preference. Take a look at this list and try some yourself. How do I connect to a pool? Most pools will give you a tutorial on how to but the basics are as follows:
Signup for a pool
Create a worker for your account. Usually one worker per rig (Yes people have multiple rigs) is generally a good idea.
Create a .run file. Open up notepad and type cgminer.exe -o (address_to_the_miningpool:port_number) -u (yourusername.workername) -p (your_worker_password_if_you_made_one). Then File>Save As>runcgminer.run (Make sure the drop down is set to "All Files" and .txt document.) and save in the same folder as cgminer. That's it.
Double click on runcgminer.run (or whatever you named it) and have fun mining.
Mining Profitability This game is not easy. If it was, practically everyone would be doing it. This is strictly a numbers game and there are calculations available that can help you determine your risk on your investments. 4 variables you need to consider when you are starting to mine: Hardware cost: The cost of your physical hardware to run this whole operation. Power: Measured in $/KwH is also known as the operating cost. Difficulty rate: To put it in layman's terms the increase in difficulty is inversely proportional to amount of coin you can mine. The harder the difficulty the harder it is to mine coin. Right now difficulty is rising at about 18% per 3 days. This can and will change since all you miners are soon going to jump on the band wagon. Your sanity: I am not going to tell you to keep calm and chive on because quiet frankly that is stupid. What I will tell you not to get too carried away. You will pull you hair out. Seriously. Next thing you will need is a simple tool. A mining profitability calculator. I have two favourite ones. coinwarz I like this one cause it is simple. The fields are self explanatory. Try it. bitcoinwisdom I like this one because it is a more real life scenario calculator and more complicated one (not really). It also takes increasing difficulty into account. Please note: This is the absolute basic info you need. If you have more questions feel free to ask and or google it! More Below.
The 21.co "computer" certainly deserves a place in the VC world, along with the other products consisting of wild promises and inane use cases. For the price of 4 Raspberry Pi computer kits, you get the following:
A Raspberry Pi. You can do a lot with this. One thing you can't do, however, is reliably run a Bitcoin node: the single gigabyte of RAM gets crowded with the bitcoin memory pool (normally up to 100 megabytes, or more when a "stress test" is taking place).
A 128 GB micro-SD card. Used to store the block chain, which is about 32 gigabytes in size right now, and growing at about 144 megabytes per day. Unfortunately, the copy of the block chain 21 Inc. includes is obsolete the second they ship the product, so you have to wait a few hours for the block chain to synchronize. This uses those valuable limited write cycles you have on your SD card.
(If you have a remote desire to develop applications that use bitcoin, stop here. Go through that list and buy just those items above. You don't need anything else. If you're looking for comedy, or if you're a sucker with too much money, read on...)
Is that all I get for my money?
Those products alone don't allow you to make Bitcoin applications, apparently. You need these things, too:
An ASIC chip and a giant fan. Bitcoin mining hardware has a propensity for running hot, so you need a fan. Unfortunately, the Raspberry Pi can't power those two items. The Pi uses a standard 5 volt mini-USB connector for power, and draws at most 2 amps. The fan alone uses three times the maximum current that the Raspberry Pi can handle. Also, a tiny fan like this emits lots of noise, so you may want to include some earplugs in your Amazon.com shopping cart. Free up another outlet for you to use, because there are two power supplies!
It's difficult to justify developing a $400 computer that can't do much. So, to entice some customers, 21 Inc. included demos that try really hard to make customers feel inspired. Here are just a few things that 21 Inc. claims were totally impossible before their product existed:
Web proxies, but with bitcoin! Gone are the days where you would pay a small fee (normally, no more than $9 per month) to access a wide array of private proxies. Now you can build your own service where you charge customers 1 cent per request to use a single public proxy. If that doesn't seem absurd yet, consider the following: loading this page probably used 60 requests for images, fonts, and various code to make the page work.
Online SMS gateways, but with bitcoin! Don't pay your phone company fifteen cents to send a single short message, and definitely don't pay a monthly fee to send unlimited messages! Be your own phone company and lure people into using your gateway. Granted, developers can use the same third-party messaging API for free, but that isn't the bitcoin way. Also, you may want to make sure you're legally a company and not an individual, just in case people want to use your message service for sending death threats to those who defame Satoshi and a few three-letter agencies charge you as being responsible.
Hey guys, I am currently trying to get into the bitcoin mining with the hopes of having a steady output of some satoshis. I am quite aware of the current state of the mining business and have run the calculations. So: I am not looking for a quit break even, I just want a steady flow of like 2000 satoshis a day. To achieve that I have purchased two GekkoScience 2-Pac and I intend to get more over time. What is missing is the USB hub. I am quite unsure what would be the best pick. What I intend to have is a hub that enables me to have like 5 of these asics pointing upwards and still having at least one, better two, ports free to also run USB fans. And all ports should deliver maximum power (14W) so that I can run the miners on full speed. Does anyone have any suggestion for such a hub? Short summary for the hub I want:
5 ports for miners
1 or 2 ports for fans
at least 14W output for each port
ports poiting upwards
ports having enough physical space between them so that the all miners will fit
I somehow guess that there is not the perfect hub I want. But I hope that at least with the help of you guys I get to the next best fit ;) Thanks in advance!

So I've been looking into Bitcoin mining, and I thought of picking it up as a hobby. I was looking into getting the Raspberry Pi 3 and getting a few Block Erupters. I've looked on eBay and Amazon, but I'm a little weary because they are sold by third party sellers, and I'm new to this. Is there any verified vendors that I could buy a good Block Erupter from? Edit: Formatting/spelling
Want to get started mining defcoin with an ASIC and a Raspberry Pi? Does 360 KH/s of mining power sound appealing? Here’s how to do it. https://pbs.twimg.com/media/Blpj8IvCcAEIStY.jpg 1) Hardware List -Raspberry Pi Model B --SD Card --Micro USB power supply --Ethernet cable -Gridseed ASIC --12V power supply (5.5mm/2.5mm barrel connector) --USB to Mini USB data cable The main component is the Gridseed ASIC, which will be doing the Scrypt calculations. The Raspberry Pi will be used as the controller for the ASIC, and will be doing the communication with the mining pool. If you’re not familiar with the term, an ASIC is an Application-Specific Integrated Circuit - basically a chip with a single purpose, like mining crypto currency. Using an ASIC will allow us to mine more efficiently than we would be able to with general purpose hardware. The ASIC that I’m using is a “300+ KH/s Single Gridseed ASIC Miner”. It looks like a CPU heatsink with a fan attached. There is actually a circuit board with 5 ASIC chips sandwiched between two halves of this heatsink, and has a mini USB connector and a power connector sticking out the side. There are a few places where you can buy these. I bought mine at GAWMiners.com for $130. That was the lowest price that I could find, and I had a good experience buying from them. Use this link, and you can get $20 off of a $200 order (and give me some referral points :-)) GAWMiners. You can also find other vendors by searching for “Gridseed ASIC”. You’ll need a 12V power supply to power the ASIC, and a USB A to USB Mini B cable to connect the ASIC to the Raspberry Pi. I’m using a 60W power supply, which seems to be working fine for defcoin (Scrypt) mining. These ASICs can also mine Bitcoin at the same time, but you may need a beefier power supply if you want to do that. The Raspberry Pi can be purchased at any number of places- Amazon, SparkFun, AdaFruit, etc. I’m using the Model B because I had one already, and also because it has a built in ethernet port that will make connecting to the internet easy. Make sure to get an SD Card and a micro USB power adapter to get the Pi up and running too. 2) Software If you haven’t already, download the defcoin wallet from defcoin.org. If you want to do pooled mining, create an account for one of the defcoin pools, such as redbaron.us or whichever other pool you want to mine. Once you’ve created a pool account, make sure to create a worker too (for MPOS pools, that will be under My Account > My Workers). The password for your worker does not have to be the same as the password for your pool account (and it probably shouldn’t be). Next, download the latest Raspbian image from raspberrypi.org/downloads/ and install the image to your SD card. Instructions for installing the image can be found here. If you are using the dd method on a Mac, make sure to use /dev/rdiskX instead of /dev/diskX - both will work, but rdiskX is much faster. Once you have the image installed, put the SD card in the Raspberry Pi, connect the Pi to your network, and connect the Pi to your micro USB power adapter to power it on. Next, SSH in to your Raspberry Pi with the default username and password pi/raspberry. I use nMap to find the IP address that has been assigned to my Pi. You can also use an HDMI display and a USB keyboard to log in instead of using SSH. After logging in for the first time, run through the wizard that comes up to configure your Raspberry Pi. The defaults are fine for most things, just make sure that you don’t skip the step to expand the filesystem to use the rest of your SD card. If you don’t expand the filesystem, there won’t be enough space for other software. Once you have Raspbian installed, and have gotten through all of the first login setup stuff (which will likely end with a reboot), log back in to the Raspberry Pi with the pi user. From the command line, run sudo apt-get update sudo apt-get dist-upgrade There are some stability issues with USB communication between the Raspberry Pi and the Gridseed ASIC. Enabling SLUB debugging seems to resolve this, at least well enough to prevent the Raspberry Pi from freezing every so often. Open the /boot/cmdline.txt file, and add the following text to the end of the line. Don’t add a new line, just add this to the end. You can use vi, nano, or whatever your favorite text editor is to do this.
Reboot the Raspberry Pi once you’ve added that flag to your /boot/cmdline.txt file.
sudo shutdown -r now
Log back in with the pi user once the Raspberry Pi is finished rebooting. The mining software that we’re going to use is a customized version of cgminer that has support for the Gridseed GC3355 chips that are used in our ASIC. There are a number of different mining programs out there, this is just what has been working the best for me so far. First, install git and dependencies needed to compile cgminer.
cd cgminer-gc3355 autoreconf -i ./configure --enable-scrypt --enable-gridseed make
Once the make command finishes, we’re ready to run the mining software. You can also run make install if you want to install the software, but running it out of the build directory works just fine. Plug in the power supply for your ASIC, and connect the ASIC to it. Connect the USB cable to the ASIC and to your Raspberry Pi. Run the mining software by running the following command. The -o option specifies your pool URL, the -u option specifies your username and the workername that you set up for the pool, and the -p option is the password for your worker. There are a couple of options available that are specific to the gridseed ASICs, and those will be placed after --gridseed-options. The freq=850 option sets the clock frequency of the ASIC to 850 MHz. There are other clock options available, but 850 seems to be working best for me. I was getting hardware errors at 900, and a lower average hash rate. I am getting about 360 KH/s with the clock frequency set to 850.
This command needs to be run with sudo in order to access the USB hardware. You can also create another user specifically for mining, or grant the pi user the appropriate permissions if you don’t want to run cgminer as root. When you run this command, you should see output from cgminer showing that it is communicating with the mining pool, and something showing your hash rate. If you’ve gotten this far, and you’re seeing output from cgminer showing a hash rate, congratulations, you’re mining defcoins with your ASIC! There are just a couple more steps to do if you want to let your Raspberry Pi and ASIC continue mining without needing you to be logged in. To keep cgminer running after I log out, I am using nohup. You could also use screen instead of nohup. Create a script (startMiner.sh) by running the following commands.
If you run this command with sudo startMiner.sh, cgminer will run in the background, and will continue running after you log out. If you want to have this run when your Raspberry Pi boots, modify your /etc/rc.local script so that it executes this startMiner.sh script. Your /etc/rc.local file will end up looking like this:
# Print the IP address _IP=$(hostname -I) || true if [ "$_IP" ]; then printf "My IP address is %s\n" "$_IP" fi /home/pi/startMiner.sh exit 0
What is your intended use for this build? The more details the better. I’d like to build a gaming/mining rig. I would like to run 6 graphics cards at one point, might not buy them all outright. So the goal. A gaming computer running the 1070 separately so I can still game and do stuff while the other 5 cards are mining. When im not using the computer, I have the option to put the 1070 to work as well. Is it a stupid idea to combine the two purposes into one super computer? Also, I’m having trouble finding a compatible motherboard and would love suggestions. Finally, I have tried reading on the riser connection info and I’m still not sure. Hopefully those are the correct risers? If gaming, what kind of performance are you looking for? (Screen resolution, framerate, game settings) Nothing too crazy. I have done the research on that side of things and the things selected should make me happy. What is your budget (ballpark is okay)? $2000-3000 (depending on how many gpu’s I buy at onece) In what country are you purchasing your parts? U.S.A (amazon, here is the link my current list. https://www.amazon.com/gp/registry/wishlist/2NAC9YOHISTRI/ref=nav_wishlist_lists_4) Post a draft of your potential build here (specific parts please). Consider formatting your parts list. Don't ask to be spoonfed a build (read the rules!). CPU: AMD Ryzen 5 1600 Processor with Wraith Spire Cooler Motherboard: Im not sure!

MAD Doge - Such Problems, Much Solutions, Year of DOGE. (March 30th, 2014)
MAD Doge – 3/30/2014 The epic battle in price PANIC! PANIC? Well yes, panic if you want, it’s apocalypse time.
ASICs - What's wrong with efficiency?
ASICs concentrate the mining power to connected and individuals who can either build the mining devices or fabricate the chips. Since they are application specific, the cost and availability is not held up by alternative uses.
ASICs introduce incredible hashing power which can allow 51% attacks for a cost-effective price. Additionally, Multipool effects can be multiplied as well as become easier with ASIC / GPU combined mining.
ASICs are a losing game unless you have the ability to get in on unreleased designs. Buying an ASIC without access to these designs will always leave you at a generation behind the current standard. (Look at Block Erupters - The people who purchased them for $100/piece are doomed to sell them for less as mining can never compensate their losses)
Cryptocurrency is considered a property for taxable purposes, this can cause problems since there are a variety of ways this can be considered, referencing transactions for new transactions will cause a variety of exchange rates to be concentrated at one transaction and the change in value overall has to be calculated for it to be reported on your W-2 tax form (For the USA MAD Doge's)
Cryptocurrency exchanges might accept this and fight to keep this since you will be required to use a cryptocurrency exchange or similar group to track your transactions for taxable purposes. This ADDS additional transaction fees that go directly against one of the core goals of BitCoin...minimal transaction fees - VIDEO LINK (Notice anything that has changed since the generation of this video?.
The need for DogeCoin to have a higher value
DogeCoin needs a higher value as time goes on in order to keep people mining and to avoid the profitability of a 51% attack. Unfortunately, the last halving has left us at only an increase from some of the lowest numbers to around 120 satoshi. Even though this is above double the last average low (58 satoshi), this is actually lower in tradeable value as DogeCoin has dropped with BitCoin to less than the comfortable average of $0.001/DOGE - Side Note: If you're reading this, reply to this post with a joke, I'll tip a bunch.
DogeCoin Value can increase one of two ways and a variety in between: A jump in mining cost and overal hashrate (all else held constant) or a jump in DogeCoin demand. Some might think that ASIC's are a great solution since the hashrate will jump through the roof, however this is foolish. There will not be a cost rise overall since the price to mine will drop as these new asics are rolled out. The difficulty will rise and mining will be backed by a smaller group that mine at a lower cost, thus the new miners will be willing to sell for less.
What am I doing? How am I invested in a solution? (WOW SUCH LONG READ)
I mine via GPU's, my current hashrate is 700-900kh/s. I am running 7790 graphics cards and have recently switched to two 270's which are at 420kh/s average. They're not getting much return, but at least I'm helping keep the system from being 51%'d
I invest in new cryptocurrencies, even if they lose me money (I have lost $50 in new cryptocurrencies) since it is important to buy in to new cryptocurrencies in order to keep their value up so that the development keeps improving. I invested in KGW (Kimoto's Gravity Well) based currencies and Scrypt-N (which I refuse to mine...yet) proof-of-work currencies as well as ones that offer unique improvements to everyday cryptocurrency problems.
Pushing for a solution to ASICs in the order of finding a new way to do Proof-of-Work that is highly efficient on GPU's and CPU's so that anyone can mine equally and profitably (If they are willing to do so).
What's going to happen?
Prices are going to drop until we get a permanent solution or higher demand for DogeCoin. People right now have other larger problems to worry about and will focus on them primarily. Watch out for the price drops near USA Tax Day (April 15th) and possible April Fools price fluctuations if people take fake stories seriously.
Watch out for DogeCar, the price is definitely going to rise, but it's going to be a hard sell since we're basically trying to sell a precious metal now (according to USA's IRS), if you think that's easy, google search gold informercials since gold is also a property.
Prepare for a fork, if new ASICs come on the market and dwarf the current hashrate, a 51% attack could cause us to fork, similar to how AuroraCoin forked. This could also cause Multipool-type shenanigans again.
It's going to be a rough ride, but there are upsides, Cryptsy has started on USD/DOGE exchanges.
Looking for a beginner hobby project: Is a Raspberry Pi controlled ASICMiner Block Erupter USB array worth my time?
Hello! I've been wanting to get involved with bitcoin mining for a while and thought that bitcoin black friday was a great time to take the plunge and order some hardware. I don't have the money to invest in hardware that would actually provide a net profit, but that's not really important as I'm interested in getting involved as a hobby project. I recently came across this PiMiner Raspberry Pi Bitcoin Miner kit/tutorial and it looks quite interesting. My question for you guys is if you've had any experience or know of any flaws with this setup or even if this is so outdated now so as to render it useless as a miner. I suppose the big unknown for me in this setup is the ASICMiner Block Erupter USB devices. Is there a better mining hobby setup available in the same kind of price range? Would the raspberry pi controller work with a better alternate USB ASIC miner? Thanks for taking the time to help me get started with this hobby!
If malicious hackers can pool together tons of phones together to reach considerable hashing power; Can a positive community crowdsource a large batch of cheap USB miners with auto-p2pool configurations? A significant amount of small parts add up to a greater sum!
We now hold the discussion about the danger of GHash's strength, let's use this energy to make a difference. Let's use frictionless money to make it easy for a bunch of small contributions to make a big difference. Ghash is popular because it's easy to mine at any amount and get a small payout, even if it doesn't quite break even. P2Pools offer the same advantage because there is no middleman to collect fees. Yet until P2Pools get larger hashing power, this makes it not advantageous for small miners to individually direct towards P2Pools.. Yet if a bunch of small miners directed towards a single pool, it can make a significant difference Developers have already created bot-net type applications that use phones to pool together and mine. It has occured on iOS, Android and has been occurring since 2011. So if developers can do this maliciously, could we use this same mentality in a beneficial way to easily and cheaply secure the network? Currently you can get small USB miners for a few bucks. And if you want to spend a little bit more, it's easy to get a hub/dock to group more then a few miners together. Yet even just running one device in the background while online would be useful if many people did this. So what can we do? Well the best way to coordinate an effort would be to crowd-fund a kickstarter like campaign to buy a bulk amount of USB miners so that people could spend a few bucks and get a miner or two to give to friends. It would be great to get a large vendor trying to rid stock could do something like this perhaps? Ideally I would like to use Lighthouse yet it is not ready. I am unaware of any other decentralized crowd-sourcing applications. If nothing else arrises then Bitcoin Starter could be a substitute for such a fund. How many people would be interested in running a small USB miner in the background while your on your computer? If everyone pitched in a buck or two to get a small miner shipped to their house, would you run it? Please give your thoughts! If you can help please stand up and if your willing to support make that known! If you think this is stupid then say so! tl;dr: let's see if we can get a community crowdsourced effort to distribute small usb miners to a crowd of people. If they all pointed their dust-amount of hashing power it could add up to a greater sum. If done with a P2Pool it could be a very beneficial action to secure bitcoin's decentralization.
Someone please proofread what I have written below, so it can be posted on r/environment and other such subreddits.
Here is the title. Bitcoin requires a tremendous amount of electricity to be maintain, but there are much more environmentally-friendly, alternative cryptocurrencies. Please demand that merchants accept the environmentally friendly alternatives. Executive Summary: Large Bitcoin mining operations are now being constructed in places where they unnecessarily squander the least expensive, renewable hydro-electric and geothermal-electric resources. There are very environmentally-friendly, readily-available, alternative cryptocurrencies such as Blackcoin and NXT that do not pose a threat to these precious renewable resources. The environmentally unfriendly coins that require a lot of electricity to mine are called Proof of Work (PoW) coins. The environmentally friendly alternatives like Blackcoin and NXT are called Proof of Stake (PoS) coins. The price spike in bitcoin last fall has led to an arms race to adopt electricity-gobbling, specialized mining equipment in the pursuit of corporate mining profits. They were not required to maintain Bitcoin prior to their invention. Specialized mining equipment for a second class of coins, which are similar to Litecoin, another PoW coin, is about to start shipping. This will lead to another large surge in unnecessary corporate mining operations and greatly increase the electrical demand in the race for corporate mining profits. You can read the long report below.to find out more about the issue, and you can visit blackcoin and NXT at the links below to find out more about our coins. If you have heard enough and just want to do something quick and simple to support our efforts, visit blackcoin and NXT, click on our subscriber button to show your support, and then watch us take on Bitcoin. While you visit the two subreddits, you can judge for yourself which one you think will succeed. Hopefully, some respected environmentalist will start campaigns to get merchants that already accept Bitcoin and Litecoin to start accepting the environmentally friendly alternatives. http://www.reddit.com/blackcoin http://us.reddit.com/NXT/ Electrical requirement to mine PoW coins: The Bitcoin, Litecoin, and Dogecoin ledger are maintained by miners who compete against each other to see who can first find the next page for their blockchains. Only the miner that wins the race for each ledger page gets paid in coins. As a result of this competition and the late 2013 price spike, Bitcoin mining corporate startups are popping up in central Washington State as documented in the first link below to take advantage of the inexpensive, renewable hydro-electricity and in Iceland as documented in the second link below to take advantage of the renewable hydro and geothermal resources. If bitcoin continue to expand, it will unnecessarily eat up more and more of these valuable renewable resources Link to Washington State Bitcoin mining article http://www.spokesman.com/stories/2014/ap26/northwests-cheap-power-drawing-bitcoin-miners/ Link to Iceland Bitcoin mining article http://dealbook.nytimes.com/2013/12/23/morning-agenda-the-bitcoin-mines-of-iceland/?_php=true&_type=blogs&_r=0 The next surge in electricity requirement is about to happen: The mining hardware manufacturers are about to start shipping specialized mining equipment that can only mine the Litecoin and Dogecoin type of PoW coins as documented in the two links below. This new front in the mining arms race will gobble up much more precious renewable electricity in the competitive pursuit of corporate mining profits than is currently required to update the ledgers of these coins. http://www.cryptocoinsnews.com/news/innosilicon-a2-terminator-scrypt-asics-first-28nm-chips-litecoin-dogecoin-mining/2014/04/30 https://coinreport.net/zeusminer-pre-orders-scrypt-asic-miners/ http://www.coindesk.com/mining-roundup-multipools-doge-amazon-ec2-11ghs-usb-sticks/ This specialized equipment is prostituting the original bitcoin promise The tremendously profitable mining of crypto coins that are competitively produced is unnecessarily prostituting the original concept of their inventor, Satoshi Nakamoto. He envisioned bitcoins as being mined on standard personal computers while preforming other useful tasks. Instead, special computer hardware is being manufactured costing upwards to $10,000 apiece which can perform only one task. These individual units are being racked up in warehouses now. This specialized equipment was not required for Bitcoin prior to its invention and is not required currently for Litecoin and Dogecoin. However, it is coming anyway producing an unnecessary arm race in the pursuit of corporate profits. These specialized dev ices are energy inefficient in a second ways. These specialized devices generate so much heat that they require elaborate energy-intensive cooling system for large operation. One of the most elaborate of these cooling systems is documented in the link below for a Hong Cong corporate mining operation that emerges the energy-wasting equipment in boiling goo to keep it cool. Thus, not only does it take electricity to run the equipment for these large operations, but more to keep it all cool. http://www.theverge.com/2013/12/2/5165428/bitcoin-mine-in-hong-kong-uses-jelly-to-keep-cool PoS coins are the environmentally friendly alternative. In contrast, the ledger pages of coins like Blackcoin and NXT are generated by stakeholders who cooperate to perform the task which are being done on standard multitasking computers. Many of these computers would be running anyway as originally envisioned by the inventor of the blockchain.

Litecoin mining with a Raspberry Pi: Is it possible?
I'm not looking for anybody telling me it'll be horribly inefficient. I already know that. I'm mainly just doing this for a little bit of fun. I know Bitcoin rigs are possible, but what about Litecoin? I found these USB ASIC miners on Amazon and I could just put it on a USB hub and power it with the Pi, but are there any mining programs that'll work with it?
Side effect or rising bitcoin prices: rising bitcoin mining hardware prices
A month ago you could pick up USB ASIC hardware for less than $40/US. Now the price has risen to over $80/US. I think it's an interesting indicator, and a possible indicator of how many people are flocking to Bitcoin mining late in the game.
