I've been looking for an upgraded video card and found a NVIDIA GeForce 6800 Ultra on Craigslist. The card is a big improvement over the old one (details here). Included with the video card were 2 G5's that don't boot. One is a 1.8 PCI-X - poor condition, case is damaged. The other a 1.8 DP PCI-X - fair condition, case has scratches and marks. Neither unit has a hard drive and the memory modules are odd - literally (3 in 1 unit and 5 in the other). Both had AirPort Extreme cards, no antennas. At some point I'll inventory them, clean and test the dual processor unit. Being the same model as the G5 I'm using I will keep it for spare parts.
