Please note: these thoughts and experiences are my own, your mileage may vary.
One of my passions in life has been computers since I was young, later turning into a passion for building custom PC systems. Much of my experience is from a gaming perspective then branching out to meet my customer's needs. Depending on the application and customer I've built simple internet browsing boxes for as little as $300, all the way on up to the $4000 SLI gaming monster. Every time I built a system, I felt a great sense of satisfaction and accomplishment...
Too bad those feelings never last and I have the itch to create again soon after! Building systems had as much of a hold over me then as it does now, stopping me in the middle of the day to spec out systems I've been building in my mind for hours or even days. So many options for some many different applications, gaming rigs for hardcore and casual gamers alike, and rigs for crypto currency mining.
Despite what you may have heard or seen elsewhere, crypto mining in 2018 is
not dead. The whole point of crypto currencies is to be a decentralized currency and in order for that decentralization to be maintained it requires individuals to take up the GPU, (and to a lesser extent) the CPU (web browser mining) and HDD (burst coin) to keep things decentralized. The crypto currency movement is attempting to avoid the pitfall of the majority of currency falling in to too few hands. More on that at another time. Albeit a new hobby for me, I feel like crypto mining fits in to what I'm passionate about so seamlessly, it would be a shame to miss the opportunity to partake in something new and exciting.
In my endless quest for knowledge I was curious what it took to make a basic mining system for the newcomer to the crypto mining scene. I started digging and found I already had experience building a beginning mining system and I didn't know it. I like to be as cost effective as possible in any system build I do but in the interest of overall speed and perceived longevity some parts could go lower. I will provide a parts list and direct links (if you use the links to buy I get a little kickback to help keep the blog going) to the parts I'm talking about. I have no love for Intel over AMD this is just a basic build for a beginner using the cheaper of the two components. The biggest deal is to plan out your system before you buy or build, if you plan out your system, you can better avoid common pitfalls like part incompatibility and plan for the future but be aware of how many video cards you plan to start with.
Parts List:
The CPU isn't really used all that much in a mining application and a Ryzen 3 is a bit of overkill for the build but for the purposes of re-purposing later it is a solid choice.
Recommended CPU: AMD Ryzen 3 2200G
buy
You should avoid motherboards with mining or crypto in the name as these will be over priced for what the beginner needs. Just make sure it has several PCIe 16x and 1x slots (3 to 4 total is plenty).
Recommended MOBO: ASRock AB350 Pro4 AM4
buy
The system RAM needed is only 8GB and you don't need fancy heat spreaders, so you can save some money there.
Recommended RAM: G.Skill Ripjaws V series 8Gb (2x4GB) F4-2133C15D-8GVR
buy
Storage is mostly a personal choice based on where and how your mining wallets are stored, for this build we'll be using a 120GB SSD for simplicity, this will cover OS and any mining software you may need.
Recommened SSD: Mushkin Enhanced 120GB SSD MKNSSDSR120GB
buy
Cases are hard here, the idea behind a case is to hold all of the important bits of your system, however, as you use the PCIe 1x slots they'll require an additional hardware piece that will allow them to hang outside the case. A good side panel that comes off easily is best. Again try to avoid anything that says gaming on it as it will be overpriced. Look for an ATX mid tower case as this won't take a super amount of space and will offer options for expansion. In the end, no matter what, good airflow is absolutely key!
Recommended Case: VIVO Micro-ATX (CASE-V06W)
buy
The PSU is again subjective, this is where your planning comes in, if you plan on using no more than two video cards to start with, then a 600 Watt PSU will be the absolute minimum needed. I recommend at least a bronze power rating more if you can afford it.
Recommended PSU: EVGA 600 B1 100-B1-0600-KR
buy
So far the build is pretty simple, but the GPU is where the high barrier to entry comes in. Cost vs mining potential (as of 2018-05-07) is in the realm of the nVidia 1060 6GB, 1070 (ti), and 1080 (ti).
Recommended GPU: EVGA GeForce GTX 1060 6GB SC 06G-P4-6163-KR
buy
The OS can be Windows or Linux here for simplicity sake I'll use Windows.
Recommended OS: Windows 10 Pro 64-bit
buy
I only spec out a single gtx 1060 6GB card in the build to keep costs lower as that is the single most expensive part of the system. All in all, the system would do well and net somewhere between ~$1.98/day and ~$1.04/day profit after electricity calculation. (I use
crypt0.zone calculator to get a basic idea of what the mining potential is.) Please note these profit estimates will fluctuate wildly as the market goes up and down.
As far as mining software goes, I recommend for simplicity sake,
nicehash with a few caveats. Condition 1, use two factor authentication! No exceptions here. Condition 2, Always transfer out your earnings out ASAP. Transferring your earnings with nicehash to a BTC wallet will incur a small cost... Unless you're transferring to
Coinbase.com (If you use the link I provided and buy $100 of BTC you will receive an additional $10 in BTC free!) then the BTC transfer is free. The reason I recommend nicehash.com is because it is simple to start and easy for a beginner to use AMD or nVidia GPU.
Again these weren't the absolute lowest specs for a basic mining rig, but it is a solid choice no matter what. I hope to add information on how to under volt and over clock the GPU in a future post to extend the life of your GPU. In the mean time I hope some of this information helped shed some light on the crypto currency scene. Good Luck! Please leave a comment if you have any additions or have built your own using this list, I'd like to hear about the build experience.
