Thanks pal
It can get quite expensive especially when you start putting GPUS into the loop which i intended on doing if i ever find a block for my card .
Well I have no need to water cool my CPU, I have a 120mm Apache Black running at 600rpm and it keeps the CPU below 60 degrees at 3.8GHz under Prime95.
I'd want to water cool my GTX 680 though which would cost me a fortune to do it in a way that looked nice.
