Very close. But that beast looks to be 6-8 Rack units which nets 50-75% rigs per rack compared to my solution. Also you have PCI brackets still on the cards for mounting and power below the cards which is a terrible idea for heat.

*And why would you put all that hardware in a rig and use a 3.5" non SSD hard drive?

The Power supplies are in the back under the cards to have the power connectors to the rear.
No heat is added as most newer PS'S ext to the back.
The hard drive is an example any drive bracket can be made.
I plan on doing these as kit (build your own) systems with options like rear card supports, extra fan banks, MB under GPU for standard risers and PS to the front.

The issue I see is that you are drawing heat from the GPU's and pulling it into the PSU, It's likely better than my solution which spits PSU heat into the GPU's but it's still going to heat up the PSU a lot. Especially if you are like me and load up PSU's to 90-110% 24x7

Here's a quick concept update in 4u.

Can you put 140MM fans in that center bank, make the gpu's center mounted vertically so there is room above and below, leave the space between the gpus open on the back of the case so air can flow by the cards (needed for non reference model cards)
