Typical hardware

I would nix the CD-ROM drives unless there is some real need
for it (beowulf mp3 ripper).

Don't forget some type of serial console and real estate for it.

I haven't seen a case designed to accommodate two motherboards.
Is this a commercial product?  Or are you doing a back and
front side arrangement?
