I'm not sure about mounting these two rads on top and bottom of the case. I saw really many water cooling setup in this case, and in my opinion if you use rad on top and bottom (even 2x120 which is more popular), it ruins look of the interior, mobo is like a sandwich between rads, partially covered by both of them. Unless you want to close case with no window that shows interior. Instead I would use two 1x120 rads mounted on both default 120x120 holes. Sure it would be slightly elss efficient than 2x 3x120, but requires much less modding, and looks cleaner.
