I just built a 3.06Ghz Intel P4, 800Mhz FSB, 1Gb 400Mhz DDRAM, 48X Burner, DVD, Geforce 4 128MB, 120Gb HD, 8 USB 2.0. 4 1394, Front media card reader/writer, 10/100/1000 ethernet, 17" LCD Flatpanel Display, all in a full tower case with a 485W pwr supply. Had it built and win2k installed in under 2 hours. You could have done it too.

Good luck, and I really hope you like it.
