Noise is easy to deal with, just put it in the attic I've got eight 120GB drives whirring away up there at the moment, but the case has space for eight more. I may run out of PCI slots for the drive controller cards first, though. I did upgrade the PSU to a 550W one in advance of adding more drives, but haven't got around to the actual adding bit yet.
