Case's arnt all about fans, though if you want a lot of them (and big ones at that) the Coolermaster HAF-X wont disappoint. http://www.newegg.com/Product/Product.aspx?Item=N82E16811119225
1x 200mm TOP (with room for another 200m, or 3x120mm if you have a water-cooling radiator)
1x120 or 80mm (i forgot) GPU Duct (optional)
1x80mm GPU bracket. (optional
If you really wanted more, tape a 120mm to the bottom and suck air through the grill there (optional) or put a 120mm in some spare drive bays (may be tricky)
Then whatever fans are on your PSU (which could act as an exhaust if you wanted), GPU and CPU.
