Run linux software raid - which is probably what the low-end NAS boxes
do anyway.  Raid1 or 10 have little overhead - just avoid raid5.

Plus you are stuck with whatever software they happen to run whether you
like it or not.  One thing I'd recommend that will add some complexity
on a PC though, is putting the system on its own disk (or raid set) with
the backuppc archive on a separate set.  You don't absolutely have to do
that but it will make life easier later when you want to separately
update/change the OS, move to a different box, or swap in larger drives.
