he has a PCI express slot, my 12 year old PC has one of those.

Ehhh, he makes a reasonable point, actually. That was around the time when PCIe was just starting to see widespread adoption, and a lot of chipsets (including my AMD 64 3400+ system at the time) still had AGP 8x. If its an "older" P4, it may not have one.
