You need to supply more information:
GPU size in length
Motherboard size(ATX, uATX, etc.)
Style (LED, Tempered glass, etc.)
I would recommend a microATX case because people who buy ATX cases usually need the ram slots and IMO its just paying more money for more features you don't need to use. the Rosewill FMB-X1 is a plastic panel micro/mini I/A TX computer and personally i'm going to make my build a mini itx.
