Good article but would likee to add that a closed loop water cooling setup is very easy to setup compared to a build from scratch setup. With a closed loop kit you never have to worry about adding liquid, it comes pre-filled with liquid, all hoses are connected, Kits from Corsair Thermaltake are reliable and affordable at $100-$150 depending onthe radiator size. Kit includes everything you need to install. There usually set up to cool your CPU only so it's not difficult. Just make sure it'll fit in your case. As with any PC parts or upgrade, do your research before you buy. I just built my first watercooled system so I felt obligated to share.
