I bought my system off ebay for 906$ to my door
Koolance liquid cooled pc2-601bw (black liquid cooled case)
soyo p4x400 dragon ultra motherboard (onboard everything, except video(that's a good thing))

p4 3.06 hyperthreaded 533 fsb
512MB Corsair low latency PC3200 (400Mhz ddr)
ATI Radeon 9700 pro
WD 40GB 7200 rpm 8MB Cache hdd
48x12x48 lite on cdrw
it overclocks quite nicely, have it running rock solid 3.52Ghz at 29 degrees celcius after 3 hours of quake3 arena running 1600x1200 all details on. I like
if you go AMD, get a barton 3000+ or 3200+
for the video card.. I'd wait just a little bit and get a radeon 9800 pro 256MB.. that thing will decimate anything nvidia has out

the new raptor hdd is looking nice.. 10000 rpm eide, a little pricy, but give it time. also get a hdd cooler, either air or liquid depending on your setup.
as far as cooling.. go liquid cooled, and buy copper chipset blocks for your chipsets (onboard and video card). These will dramatically increase stability, and a good dual rear single in fan should be enough to cover the rest.
