It really depends on what resource you are going to run out of :-)

But seriously, my guess is that usually you run out of RAM first.
So I would lean to

  amd64 motherboard, with lots of cores
  as much RAM as you can manage, maybe 32G
  dual 2T disks, in raid1 via raidframe on the dom0

I then use files on dom0 via vnd, but others have reported good results
with lvm, so I would be tempted to learn that.  Raw partitions are too
annoying because at least my world changes.

I advise making a list of the domUs that you are going to run, and their
disk/ram requirements, and make sure the dom0 hw is at least 3x all of
that to start.
