Here's a nice case, which I chose for my friend's build:
COOLER MASTER Elite 430 RC-430-KWN1 Black Steel / Plastic Computer Casehttp://www.newegg.com/Product/Product.aspx?Item=N82E16811119227
The case itself has plenty of space, although cable management is it's drawback- it s almost impossibe to stuff the cables somewhere, so they wouldn't be visible. Other than that, this case is great, 6 120mm fans make sure all the components stay cool + it has black interior as well. If you're on a budget, this is the case for you. Recommended.
