I believe Sun still has an open FCO (Field Change Order) out for the Ultra
1's.  If you call them up they should be able to upgrade your motherboard
to the later rev (with just a huge heatsink) regardless of whether or not
you're the orignal owner.

If you really want to go this route, try Digi-Key (www.digikey.com).  I
recommend getting the board upgrade, though.
