That makes things easier.

I think your biggest hurdle is probably SATA support.  I don't have a specific
recommendation on motherboards, but what you should do is figure out the range
of kernel versions your distros cover.  If one of them has a really old kernel
( < 2.6.9 ), you might have some issues with SATA support.  If they're all
fairly new (2.6.20+), you should be ok.

The key thing is to figure out what chipset the motherboard uses.  Then you
can (fairly) easily check for SATA support.  This document is coming up on a
year old, but it should give you a feel for what definitely /is/ supported:
