I use one of these:

Coolermaster CM Stacker. Loads of drive bays, lots of fans I have 2 x 12cm fans (1 front and 1 back), 3 x 8cm fans 2 at back and 1 on top, a 300mm cylindrical crossflow fan which blows air above and below the motherboard plus the fans in the PSU which, on this case, you can fit at the bottom if you want
I got it from overclock at

but they only have the silver in stock just now - I got the blue one
Oh you can also fit BTX motherboards by rearranging the case which is handy if they ever become prevalent
