I'm selling my Pentium 4 3.6 ghz box (it's overclocked from 3.2 ghz).
It has:
A Radeon X700 PCIe 256 megs VRAM
3 Firewire ports
4 USB 2.0 Ports rear, 2 on the Front
Gigabit Ethernet onboard, second 100 mbit Ethernet Card
Onboard 5.1 audio
DVD/CD-RW Combo Drive
1.5 gigs of DDR2 memory
120 gig sata hard drive
Also, just for you, I'll either add a CD-ROM drive in the second CD drive bay, or a 40 gig IDE hard drive. It only has one IDE channel onboard, but if I could I'd add both.
I'm asking $1000 + buyer pays shipping. I'm in Seattle right now. If you feel I'm asking too much feel free to make an offer, but this is one fast machine. It does have HyperThreading. I built it myself. I'll post pictures on request.
