Newisys came out with one of the first Opteron motherboards, and their
2 cpu motherboard is still shipped by Sun as the Sunfire 20z. It's
a pretty expensive motherboard, but the % added to the final price
depends on how much memory you buy and which cpus you're using.

There are a *lot* of clusters out there using that Tyan motherboard.
I don't think anyone's decided that it's any less reliable than any
other low-end server motherboard.
