Loud & Fast, I'm trying to understand your built for a while now... Don't get me wrong, I like it!
Just wondering what was the concept behind it?
I got the part that you wanted a better cooling for the VRM, NB and SB - the X58 systems can run hot on those points. I also can understand the reason you choose the water cooling on them. It's somewhat strange that you have the mobo on water and kept the cpu on air - but hey, actually may work.
What I can not understand, it's the position of that radiator. At the beginning, when you cut both sides of the 5.25 bay, I thought you would place the rad inside, with a side-to-side airflow through it. Then you placed the radiator outside and added two fans on the front - vertical to the radiator... Why did you cut the right side of the 5.25 bay then?! Are you planning to add a second radiator on the other side?
Did you considered placing the radiator in a frontal position, thus you can have a straight airflow through it helped by those two front fans? I think, actually you would have a better cooling effect... And if you would be worried about the noise, there would be the same amount of fans...
