My wife out of town for a few days and returned with an HP Pavilion 533w.

2ghz Celeron

768 MB RAM (1x512MB, 1x256MB)

DVD Combo drive

60 GB hard disk

Motherboard with bad capacitors (oh well - no AGP slot anyway)

Working P4 power supply

While it won't boot on its own I should be able to get the P4 2.53ghz system I found to work now that I have enough parts.
