Overclockers Online have posted a new article titled, Compressor Water Cooling, where they build a compressor based water cooling system! Heres a snip:

    "Also cutting a lid out of styrofoam, for the top of the water cooler would help keep the water chilled (keeping heat loss to a min), as well as some pipe insulation to cover the hoses.

    You will notice the back of the water cooler getting warm, placing a small boxer fan at the bottom blowing on the coils on the back will help improve the effectiveness of the unit also prolonging its life."
