I havent been around much lately, so i just found this threat and was amazed. Congratulations! I've had this idea of combining a big passive heat sink with watercooling since I finished my last build, but i was always afraid of corrosion of the aluminum if you use standard watercooling components made of copper. Did you encounter any of those problems? What watercooling components are you using and whats the size of those heat sinks?
