While surfing around on this boring friday evening, I came across this interesting article on Tom's Hardware Guide. Here's a summary, Koolance offers a very powerful barebones water cooling system. It has done an excellent job at reworking the PC case, which is delivered with the cooling system already filled. This system is ideal for AMD Athlons and Intel Pentium III chips. Quality doesn't come for free, though - Koolance charges about 250 dollars, including the power supply.
