Finally finished
6x GTX1070 and 6x GTX1060 running on 2 Biostar motherboards.
Pulling in 335mh/s of ethereum combined at 1300W from the wall.
Each GPU is blowing hot air to the back, and in the back there are 2 layers of 3 fans placed horizontal to push all the hot air upwards. The top of the cabinet has vents.
