I could always use more RAM for the 8500 and if you have one the whole rear plastic piece. The whole piece that has those 4 screws. Not a big deal, but mine has broken retention tabs.

The machine is still running strong. Right now it has a 500MHz G3 CPU in it, a Rage128 and an ATA/133 controller card. It's fast as heck. Currently running 9.1 but I want to re-partition the drive and see if I can get a dual 7.6.1 / 9.1 system going.
