CoolerMaster CM690 Case Review
 

Sometimes CoolerMaster has a hit, and sometimes they have a miss, like any company. The CM690 however is most definitely a hit. They managed to somehow fit everything from a full sized tower into a mid, and not sacrifice anything. Not only are you able to fit 2 8800GTX cards in this, the placement of the fans and the case venting all around helps keep the temperature down. There's even room for a few more fans on the side, front, and even the top if you feel this case isn't staying cool enough.
