Running your standard 4400 cpu, 16gb ram, biostar 250. I have another 1060 on the way to max out at 6 and 6 nvidia/amd and two radeon 470's on deck once all six nvidia cards are dialed in. If anyone is interested I have a pretty solid method for overclock and power on 1060's and 970's if you are running old shit. Total watts is 553 w/ a intermediate 1100 backup power supply and a corsair 1200 with plenty of room to breathe.
