I don't remember them. Its 5 years old. What I could gather from looking inside:
PSU: Antec 450W Smart Power (SP-450)
RAM: Corsair 1GB 184-Pin DDR SDRAM DDR400(PC3200) (2 x VS512MB400)
GPU: NVidia GeForce 6600GT 128MB
MoBo: MSI....MSI K8T Neo-FIS2R (MS-6702 ver 1.0) (http://www3.dealtime.com/xPF-MB-MSI-VIA-K8T800-K8T-NEO-FIS2R-RT)
CPU: its AMD but I don't know what speed. Athlon something or another but I can't tell by looking in the case and I don't recall.
I have several HDs, a DVD-RW, a tuner and Audigy 2 ZS in there as well but for reasons listed above i don't think they are the cause
