[rescue] Difference between U5/10?

I'm pretty sure the UPA slot is on the board itself, and that the U10 is
the only case that's high enough to accept a UPA card in the case. If you
look at the rear of the U10 case, there's 5 PCI slots (IIRC) that are
parallel to the motherboard plane (therefore coming off of a riser card),
but there's one slot that's perpendicular to the motherboard plane
(therefore directly off of the motherboard). This slot is the UPA slot.
So an Ultra 5 *COULD* take a UPA card, but only if you took out a hacksaw,
or found a U10 case and PCI riser.
