Another nod for the addonics stuff.    I run their 5 hdd hot swap bay in my
master backend/fileserver, connected into there 5->1 PM, connected to a 1x
PCIe card. I think the 1x lane of PCIe is the bottleneck, but I don't
notice. Been running that setup for 18 months

Also agreeing with the fact that you don't need crazy power for drives...  i
have 11 seagates humming, with a 2.66 GHZ c2q and an nvidia 8600 all running
off of a 550W powersupply.
