Well, as much as I am for AMD, I'd just like to point out that Intel hit that speed over a year ago w/ a retail fan that has a heatsink the size of a half dollar.

Anyways, i finished my watercooling system from scratch. Pics:
NOTE*** My dirty wet pants and socks in top left of first picture were from when i first turned the pump on. Appearently you do need the exact size hose

Yeah, there was a leaking problem, but i solved by getting the right sized hose. ID (inner diameter) and OD (outer diameter) are truely too confusing... I had a different size barb / fitting on every device i had.

Most are relavent, first dozen are so were old pics left on the camera
Idles at about 80F w/o CPU idle, 74F w/ CPU idle. Full load is 86F.
System Specs:
AMD Athlon Thunderbird 1000
MSI K7 Master
256MB PC2100 DDR RAM
Voodoo 3 3000
30GB Western Digital HDD
NOTE*** Ordered a new AMD Athlon XP 1600+ that will arrive next week, unlocking kit (from highspeedpc.com), and a digital thermal probe. I'm also getting an ATI Radeon 9500 Pro soon for my main system, so my old Geforce 3 Ti500 will replace the Voodoo 3 3000. Hopefully i'll get a GPU waterblock, i know that the Ti500 runs hot and will probably limit my FSB speed somewhere down the road. Once i get this @&$#* above 2GHz i'll let you know

I'm also thinking of some vcore mods (to get to 2GHz), if anyone has any suggestions on that, please let me know... that's something i don't know the specifics of.
Watercooling Specs:
Via Aqua 1300 370GPH pump - $20
Black Ice II Copper Radiator (2x120mm Fan)- $50
Swiftech MCW462-U Waterblock - $43
Vantec Nexus Fanbus 18w Per Channel - $29
I made the reservoir myself w/ some silicone glue, 2 barbs, and a waterproof box (the grey thing on top of computer)
Other materials were the tubing (3 different sizes on mine), adapting barbs, clamps, and distilled water.
The total project probably cost about $150, but if i did this a second time i could make it a lot cheaper.
