So . . .
The Video cards works, threw it in a PC at work and confirmed. It's one of them strange thingies where the Motherboard and the Video card just don't want to talk to each other.
So . . .
Picked up 2 GB of DDR2-800MHz RAM, and nice no-frills Gigabyte Motherboard, and an Intel Quadcore Q6600!
Stuff seems to work, installing Windows now. I wonder how many virtual Machines I can run on this . . .
