I'm having much more fun with new setup.

After doing some bench marking I've realized that water cooling doesn't pay.  The H100i is perfect and cheap. I'm running my 3930K at 4.5Ghz and never pass 50C.  Instead of cooling my 7970 I picked up another 7970 that was refurbished. It was cheaper then the Komodo block and the Alphacool pump. Don't forget about the money for the radiators and all the fittings. My analysis is, only build a custom wc setup if you want it to look cool or you are maxed out on hardware. If you can still buy a better CPU or another GPU you should do that instead.
