[rescue] U20 motherboard upgrade ?- WAS: Wanted: Old Sun Hardware

I have a (probably similar) Sun Ultra 20 M2 system.  I have also noticed 
that several other list members have mentioned in passing that they also 
own similar units.

As these are x86 systems, I am curious if anyone has performed a 
motherboard/CPU upgrade on an Ultra 20?  Are there any oddities or 
particular strange parts in an Ultra 20, vs any other generic x86 based 
system that would preclude an upgrade?

I hope that this is a completely stupid/obvious question, but this is my 
first/only x86 system that I have had in over a decade.

TIA for any replies,
