Regarding the Coolermaster 832
Regarding the number of drive bays, remember that this is also known as the Stacker. It's a modular, toolless case that accepts EATX and BTX, has gobs of cooling, the lot. You can buy more HDD bay conversion modules from CM. C'mon, it's a server/extreme workstation case. I've got the black 830 version, and I think it's bloody marvellous.
I was really surprised when you said it was quiet though! I've got two 200 series Opterons and two 7900GTXs with a SCSI rack in mine, so as you can imagine it needs cooling. I filled the side fan array, got huge heatsinks, fitted fans to them, fitted a fan to the drive bay, one to the dorsal vent and two exhausts, and it sounds like a ruddy jet taking off. Worth every penny though. I just love hearing the drives spin up and down from 0 to 15000rpm and back. Bloody eats most apps for breakfast. ;-)
