David:
    Do you know of any web sites related to this?   I'm rebuilding a server
that I have and I would like to know a ballpark figure on how many drives I
could put in this box without blowing out a power supply.

Thanks,

  I've never been able to support this mathematically, but my rule of
thumb has been that each "drive power lead" from the power supply can
handle one hard drive and one other device (floppy, CD-ROM, fan, or
whatever).

  I've encountered some really strange problems whenever I have put
two hard drives on one lead -- usually exhibiting the classic
pattern where warm boot usually works fine and cold boot never does.
So I just don't do that any more.
  I think Drew Dunn recently posted a URL to his page which includes
a machine with a mini-tower case being used as an external drive
enclosure.  That, or something very like it, is what I'd recommend
for going beyond two (SCSI) hard drives.
