P4 2.4,
Asus P4E-800C (I think)
1 MB RAM (DDR 400)
Radeon 9700 128MB AGP 8X
2 WD 80 GB 7200 HDD (IDE, but running on SATA connectors) Mirrored array.
500 W ANTEC PSU.

Runs like a champ..although lately I've been getting an intermittent BSOD when I shut down BF2.
I'd like to upgrade, but PC have gone up in price, not down.
