One thing to keep in mind:

Hard drives can take a lot more power to spin up than to run.

So if your box is loaded up with 4-6 drives, you probably need a honking 
big PS even if your continuous power needs are pretty low.

Some SCSI controllers have a 'staggered spinup' feature where each drive 
is brought up by itself, followed by the next drive, and so on.  (A 
necessity - my dual channel SCSI card can control 30 drives so spinning 
up that many drives at once would probably dim the lights in the house.) 
  With new mobos having 4 - 6 SATA connectors, it would be nice if the 
drives could be told to spin up sequentially rather than all at once.

'man' is short for 'manual' because it's very short, for a manual.
