So, the powersupply shouldn't be an issue. Is the motherboard standard
form factor too? Maybe I could put it into another case.

Is there good support for a SATA card (if I wasn't trying to boot off of
it)? This could be a good solution to possible performance issues that I

This is true in either case. I would want to put in a controller that
could handle 500 gb drives. I have read that you had to have 5 volt cards
for the Sun Blade 100. Do you know if this is true?
Also, I have been using an ATTO SCSI controller and an intel 100+ pro
ethernet card in a mac running NetBSD. Both seem to work incredibly
reliably. Would they work equally as well in a Sun?
