I was looking at the Thermochill PA radiators, after hearing how they were supposed to be so great. I was getting ready to add the 120.2 version to my shopping cart, when I realized that these things cost almost $120!! Good Lord! Why are these things so expensive? I've had pretty good results with the Black Ice radiators I've had in both my previous builds, and I guess I'm going to try them again. Are these things really worth all that money?
