Hardware Wanted

WTB upgrades for my r5k 180/256mb ram O2

It's about as barebones as can be right now...
I do have the av card and FireWire pci card still...

Primary wants:
An RM5200 cpu (is it a direct upgrade over a 180mhz r5k?)
Or if there's someone willing to part, the 600mhz upgrade cup
Higher density ram

Also interested in:
1600sw adapter+panel
Compatible DVD drive
Cd cover
Granite keyboard

I'm in the Bay Area in California if that helps with costs :)
I've got the rubber dome granite PS/2 keyboard here, $20 + $17 for postage to Cali.
