Anyone built a crypto mining rig?

Yes.

Use Hive OS, highly recommend for the os on your system.

In terms of hardware I would suggest doing a bit of research. Determine what algo you plan on mining with the rig. There are some wevsites with calculators that let you get an idea of what you can expect hash rate wise for different cards.


Ultimately what you want to do is min/max your cost per hashes on planned algo. So yes, you could run 8 3090 TI’s… but does the extra price for card and additional power consumption justify the bump in gross hashrate.


You can go second hand for everything thats not the gpu’s.



Unless you’re looking at the rare cpu based algo, if you go that route make sure the cpu has an integrated gpu.

NOOOO. Don’t do it. First off, $500, $1500, $2000, won’t get you anything. There are guys who say you can mine for $100, that’s true. You could technically mine right now on your computer, it’ll just be really slow.

It is REALLY FUN to build and that first time you mine something is a great feeling. Ultimately though you have to spend SO MUCH money just to make a little bit and you have to sustain it and can’t just “set and forget” the way you think. If you leave town you’ll want to monitor it with remote PC or something, etc. Power outage while you’re at work? Internet cut out for a brief second? Have to restart. 6 months later your graphics cards won’t be the nicest ones on the market and you’ll have to upgrade to keep up.

Here’s what I did. I made the frame myself, bought a $300 power supply, $100 motherboard, $50 hard drive, monitor, keyboard, mouse, and $20 WiFi receiver. The big expense is the graphics cards which do the mining. I had the nicest cards at the time, 1080TI’s, they were all between $750-$1000 each. It was popular at the time and they were always sold out so the prices gouged a little bit but those models were never on sale for less than $600.

There’s (or was) a website called “what to mine” that tells you what coins are the most bang for your buck (worth the most in ETH or BTC) that you can choose to mine. It was almost never ETH (the most profitable mining coin would change constantly), so you would mine the alt coins and convert them to ETH because alt coins can drop to zero in 5 seconds. The BEST day I ever had, I got $7 from each GPU. Eventually the excitement wore off and I got tired of converting them every few days (sometimes every day) or dealing with my internet randomly hiccuping when I was out, then I have to restart the computer when I get home and realize it hasn’t been mining all day… etc.

In the end, I was moving from L.A. and ending up selling my GPU’s, no one cared about the motherboard/powersupply etc. and since I bought them during a price gouge and since the new models had come out, I lost about $2k. It was really really fun in the beginning though, so I considered it worth it. But as a money thing it’s not worth it.
