It's ok if it's cheap, but if I had a PC with parts like that, I'd get a quality case. Doesn't necessarily have to be expensive though. Your motherboard is ATX form factor, so a cheap high quality mid-tower case will be fine. Just make sure that the case you're getting has enough room for a 10.5 inches long card - it's how long the GTX 480 is.
Meow, how yo ulike your 4770?
