Hello,

at the moment I have about 100 GPUs in a basement room with only one open side (former window) that serves one half air intake, other half air output with each having one big radial fan.
Temperatures get a bit uncomfortable in summer though. The room is about 150m³ big and I did not separate into cold/hot side because I have open air rigs with 12 cards each.

Now I want to put the cards all in server cases with delta fans and solve the temperature problem once and for all.
Can you recommend some good cases? Most of my cards are 3 slot height though (and none are blower style cards). So that's a problem with some configurations. Since I am not restricted to have them fit in server racks, the cases could be custom sized. But I barely find cases that fit 10 cards or even 12.
I tried some years ago a case with Vegas but they did not ventilate enough due to the small gaps in between them.
I am looking for small footprint, stacked, maximum airflow, high service convenience. So I can stack them, connect the intake air so the cold side, the other vent to the hot side and end the struggle in summer.

Any suggestions what I should look for?

Thank you in advance!!

Rosewill has server cases on sale. I am using these for my vegas due to the need for dual PSUs:

But I also use these cases from rosewill that are also on sale for the rigs I can run on one psu:

Point of caution on the 2nd case though, if you have blower style cards you'll need to mod the cases to reverse the mounting bars to get the air blowing away from the front, default mount has the cards blowing air towards the front. For the money and for new cases, I don't think you can do better than these. Have to factor shipping costs in for anything you buy, cases are heavy.
