Just been looking at this build, very nice =D I have a 955 and 6970 too but on air. I'm wondering about your 955 temp. I have a 955BE at 4GHZ on air, it idles at about 35 and goes up to about 52 on load. Is 61 not a bit high for a 955 at 3.8GHZ on custom water? Cant remember exactly the max safe temp of that chip, but I think its about 65.
I could be missing something and making a fool out of myself, but I'm just interest =D
Nice job though =D I've always wanted to go with a custom WC loop but cant afford it atm and don't have the time!
