Hi!
When you are looking for a case. Make sure to get at least a roomy midtower. This for the sake of the air flow, and that you will have a lot easier job to get the cables out of the way from the fans air flow path thru the case. And not the least that even the longest video card now and for future upgrades will fit.
As for the fan set up? Get a case that can take at least 120 mm fans . And it's only a good thing if the case will come with one rear case and one top exhaust fan, as the exhaust fans are the most important ones. With this kind of fan setup, you won't have to have any intake fans really if you do not want to? This, as the exhausts will pull the air thru the case.
Less fans, will also mean less noise for obvious reasons.
Antec, Corsair, CoolerMaster and Fractal Design have such quality cases.
It wont hurt if the case also will comes with front, washable dust filters. Or buy some.
