i have a second new miner pc with windows 10, phoenix miner (you can use any mining software) in an open "miner" style case. I just built this one.
it has an atx power supply and a server power supply with breakout board and heavy duty gpu power cables purchased from
https://www.parallelminer.com/
breakout board can power several gpu's.
Also included are two gpu risers.
his doesn't have any gpu's but i have 1 older gpu to get started if you need.
radeon vega 64 8gb, an older card but it's very good for mining. I can set it up/teach how to use, if you need.
asking $300 without gpu, $500 with the vega
