I guess there are no GPU computer cases compatible with dual power supplies.

Any suggestions?

There are, but how much do you want to spend? You can get what you are looking for from Supermicro but be prepared to get out your wallet! https://www.supermicro.com/products/system/4u/4028/sys-4028gr-tr.cfm

With the specs you are looking for, you will almost certainly need to get a barebones chasis. If you want to go a cheaper route and don't mind used, look up the HP D580 G7 on ebay. You can pick one up for 500 bucks and it will already have the 2 power supplies, motherboard and processors!
