I also have a P4 1.7 GHz CPU that I pulled from an old Dell... it was working until I broke something on the motherboard trying to pop the CMOS battery out. A few pins are slightly bent, but I was able to bend them back and pop it into another socket 478 board with no problem. (This one's on eBay now).
I've got about 4 old 56k PCI modems from various old PCs if anyone has a use for them.
Open to fair offers, what I really need is a CPU fan for a 2.66 GHz P4 along with the retention clips for the motherboard. Basically an entire cooling system for the CPU as I broke the motherboard bracket and the retention clips that hold the fan down. I could also use a GeForce PCI card - nothing cutting edge, just good enough to throw in an Ubuntu box that won't do anything but run MAME and Firefox.
Figured I'd come here first before eBay, but I'll end up over there if I can't get rid of this stuff soon.
Thanks!
