I really wanna keep everything inside. I Dont like having outside extra components. Only thing i would ever consider doing is mounting some fans on the top with some fan grills. would that work?
Who was that that said,? "Your first steps into water cooling are also your first steps into case modding!".
I forgot who said that, but it is so true.
If you have any modding skills, you can always mount the radiator on top of the computer.
Just something to think about.
However you did mention you are cooling an AMD 955, from my own experience you can fully handle an AMD overclock with a Noctua NH-D14 air cooler, I have a test machine running the Noctua NH-D14 on an AMD 965BE overclocked to 3900mhz, passively with no cooling fans on the air cooler at all.
Just case airflow is all the air the Noctua is getting and it is capable of holding the temps down to be able to run Prime95 small ffts for hours in passive mode at 3900mhz, when you add the fans to the Noctua it's a true cooling beast.
My testing was to see if I used different fans than what comes with the Noctua could I attain better cooling performance, and the answer to that is Yes!
Now if we were talking cooling an Intel Sandy Bridge K-series CPU platform, that would be a different story, but we're not according to your OP, so you can get as good or better performance than you were getting with your Corsair H60, with a Noctua NH-D14, cheaper.
Just thought I'd throw that into the consideration pile.
