anyone know on average how much an upper/middle range one of these things cost? also does anyone know what they use as coolant usually? also the images i've seen so far are extremely ugly, like motherboards outside of cases with tubing coated in like 3 inches of foam spray, is this just for extreme OCers who can't stand to stuff it in a case or have moisture, or is it just not possible even with some modding? also would putting a second uv reactive tube around the cooling tubes catch moisture? or is there a better uv reactive foam i could use less of?
