[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.
