You guys have talked sense into me, and I think Ill run with 1 x 360 and 1 x 480. I have a DD Double Wide case, which has the capacity for 2 x 360 and 1 x 480, which is why I went a bit overboard originally trying to fill my case with radiators. 1 x 360 and a 1 x 480 should work well thought, since one side of the case can carry both radiators, and the other side of the case can simply be fitted with a combination of 120mm and 80mm fans to keep the M/B and RAM cool.

If I place the 1 x 480 radiator in front of the 1 x 360, with the fans on the 480 pushing air through the 480, and then into the fans on the 360, will I see much of a loss in performance? Essentially what will be occuring is the heat dissipated from the 480 will be pushed into the fans on the 360, and then through the 360 itself. So basically the 360 will be fed air which will be above room temperature, or will already be "hot".

I'v decided on the LC mainly for aesthetics. I know the XT is an awesome block, but I just don't like the look of it, I guess it comes down to personal preference. I'd like my build to remain within a certain color scheme, and I'd like to stick to Delrin as much as possible, and since the LC is just straight Delrin, its fit for the job.
