First off, none of this is financial advice. I am a crazy person that should not be listened to, do so at your own risk. With that said…
Crypto Mining is a truly fun hobby for those that dig building computers for specific purposes and “letting them rip at 100% util”. Also Crypto Mining is the “Ultimate Dollar Cost Average” (after the rig pays itself off) ways to accumulate a crypto currency.
Once a rig is complete you can “set and forget” and note the deposits into your wallet.
Parts To Build Crypto Mining Rig
USB Sticks For Boot
A USB 32 GB Flash Drive is how most boot miners. Since most have a few of these laying around and they vary in price so greatly – leaving this out of expense. Just be sure to have one. Running several instances of HiveOS on USB 32 GB Flash Drive‘s and all is well.
This example build has numbers for both:
4 x 1060 and 4 x 1070ti in action in two different rigs. This is mining ETC with the Claymore miner. Using HiveOS. A 1060 averaged 20 MH/s each and the 1070ti averaged 32 MH/s each.
4 x 1060 averaged 80 MH/s ($239.99 each. x 4 = $956)
4 x 1070ti averaged 128 MH/s ($469.99 each. x 4 = $1879.96)
The 1060’s seem to run best with no overclocking. The 1070ti’s like Memory clocked to 1400.
Overclocking for 1070ti’s (4 x 1070ti’s in OC settingsUsing HiveOS):
*Note: overclocking never ends, this is just the best found so far. Always run a GPU for 24 hours with no tuning to get a baseline to measure from.
ROI Per 4 x 1060 and 4 x 1070ti GPU Choice
There are of course many GPU’s out there. Using these two as examples since I have these actually running and can confirm.
This is from https://whattomine.com/coins/151-eth-ethash set for ETC mining. Scroll to the bottom to see a better idea (real numbers from running miners) of what the rigs can make.
Think this is calculating 10 cents per kWh, which is about as good as it gets. Find your kWh on bill, or lookup average here. At the time these examples were created mining isn’t the most profitable venture but it varies. Personally I am speculating on positive gains as ETC increases in value. Focusing on ETC here for an example, but there are endless coins to mine. WhatToMine is a great site to check on difficulty. Many miners watch and just on coins that have low difficulty and high profitability.

Most use Open Air Frames. Recently tried out a closed case. Each has pros and cons. The open air case seems to do fine without additional fans. The closed case needs fan (that come with it) running. At least the fans in the front. Also the case doesn’t have space to close… so it is a “kinda closed case”. I don’t really favor either. Thinking of making a top for the closed case and see how it cools. The two frames used shown below.
If you used the Open Air case it only comes with a reset button. These make a nice touch:

Closed and Open Air Side by Side
Most people these days are using the open air frames. A nice room fan blowing through the GPU’s will help keep all plenty cool (usually) if needed at all. This is a balance everyone needs to figure out.
GPU Risers (only needed for Open Air rig)
If you feel sparky and want to update the BOIS go for it:
Updating mining BIOS for gigabyte motherboards
*Note: found that setting the “mining” mode on the motherboard just causes issues. Crazy.
I got the biggest because may add more GPU’s. Might be able to get away with the 750 or 850 model. The 4 x 1070ti rig while mining ETC is pulling 650 Watts, and RVN 800 Watts.
Tally of Parts
Take your pick. $53 or $99
Endless choices out there. For a basic rig these help get an idea of price with 4. Even one GPU is a mining rig.
|1060 Rig Total||$1,567.34||$1,613.34|
|1070ti Rig Total||$2,432.59||$2,478.59|
Take your pick. It comes down to how much MH/s power you want. It is easiest to have all the same cards in a rig.

Run power to fans if building with case.
The middle fan how had to be removed. Not enough space (although it may be possible with a good deal of effort). This picture is with the large fans in front. I switched the middle fans with the front. Cooling was fine and much quieter. Also so far this rig does not have a lid. Remember the case isn’t going to close. The whole case idea is nice but doesn’t work as expected. I still like it. With a lid made and the stronger fans in front it’s a wind tunnel in the extreme.
It Is Built, Now What?
I am currently running HiveOS on all my rigs. Very nice way to get rolling. For this rig note that the GPU plugged into the “Long PCI Slot” will be monitor out by default. Have not had the best luck making changes to this motherboard, so I leave it all “as is out of the box”.
