I was browsing the internet and I found this beauty. I personally have never heard of one of these before this, but was thinking that I would be able to run this out of my main rig's case, and use it regularly with a frame like this to run 2 rx 580's. My only question was powering it... I was thinking about manually turing on and off an external power supply manually, but wouldn't it possibly damage the computer if they were not powered off at the simultaneously? (On a side note I have recently been useing my GTX 1070 for mining at night or when the computer is not being used).
