I wouldn't cheap out on the case. It's what you see everyday and it most likely will be there for years despite the amount of hardware upgrades you'll get. Check out the Cooler Master Stacker or the Stacker 830, depending on how much space you need. The regular (also the original) Stacker has a very civilized look, with much more space which dual PSUs and loads more room than the Stacker 830. It's full tower size but it still looks great on the desk, very good for watercooling. The Stacker 830 is a bit more expensive but it's a bit shorter in height, better choice if you don't need room for watercooling. It's actually better for air cooling since it has 4x 120mm fans (very quiet too) blowing from the side.
