Beginner's guide to watercooling your PC

lifehacker has a great article that explains how to get into watercooling your PC.

I currently use a closed-loop fixed system (Antec Kuler H2O in a push-pull configuration using a pair of Cooler Master Excaliburs) which works great for my needs.  (But my CPU does still run a little hot when I crank it up to 4.9GHz...hmmm....)
