Hey fellas I'm looking to buy a new computer casing due to lack of space in my current one (antec nine hundred), I was going to add an aftermarket cooler for both GPUs, both unfortunately the PSU blocked the lower GPU.

What'd be a good computer case?

I've been looking at the Cooler Master Cosmos 1000. Is the spacing similiar between a PSU and a mobo?

System:
Case: Antec Nine Hundred
Mobo: EVGA 680i A1.
GPUs: 2x8800GT
Psu: Antec TruePower Trio 650w.
