I can recommend the Raven 2. Heaps of fans, an unconventional design in that you turn a regular PC 90 degrees on it's head, so cool air is drawn from below and blown out the top. I bought this case mainly because I only do air cooling and needed a big enough case for my Crossfire set-up.
My only gripe - the hard drive bays; if you need to replace a hard drive, you need to dismantle the PC, pulling out the mother board out to gain access to the bays. I had to do this recently but looking at it positively it gave me the opportunity to do a major clean out of dust
If you go to LAN parties don't get this case, its very solid and heavy.

Edit: Having just looked again, I didn't realise the Raven 3 is out, it looks like they have improved the design.
