Thanks for the detailed reply, Brian.

Yea, but who *is* this guy? :)

Don't really need physical 4-way. I'm planning on 2-way dual core. 1/2U
doesn't matter, it'll be a tower case. I mostly want the 'server'
features like dual NICs and on-board video.

I mostly just want to see how two or three striped SATA drives will
perform. If the on-board ports don't perform, I can always add a
separate controller later. My understanding is that NCQ support isn't
here yet for Linux but that it should provide a boost.

I did not know that. I've seen too many 'workstation' mobos without
serial console support to make that assumption.

Not for primary storage. Mostly just future proofing here. I've been
meaning to setup a backup system using external hard drives instead of
tape. That wouldn't fly over USB 1.1.

So, Brian, having given me all that good information (thanks again),
what specific models do you suggest? What are *you* running on?
