My first two racks of dedicated machines are full... with these plus the others scattered around the office / at home I have 101 total GPUs online.
I've swapped cards in a few of the systems earlier to reduce the amount of AMD cards I am running... it's likely I will swap almost all of the AMD cards to GTX 1060s or 1080s.
Are you running 3 GPU's per rig? i was looking at your picture it looked like you had 1 gpu in the system and 2 outside on what appears to be flooring planks?
Question for you on the power, how come your using the internal PSU over external PSU on the GPU's? I ask because the system has a very low quality PSU in my understandings that wastes away like 20% of energy as heat above 50% load.... i have been running mine all on external server PSU's because of this issue to try to cut electricity cost.
For RX480/580, GTX1070, and GTX1080 I am running 3 per rig. For GTX1060 (and my single RX560 system) I am running 4 per rig.
I have replaced all the PSUs in everything other than the Dell's with 750-watt Platinum PSUs (using factory 875-watt Silver PSU in the Dells) -- they are still very efficient at the load range I use them at (I keep them in the low 500s range [adjusted with a Kill-A-Watt] where they test 90% even when hot):

Also if one system has a problem I'd rather it be completely separate from the others so it doesn't take down other systems with it.
Not that the server PSUs are a bad idea by any means -- just not what I wanted to do.
