I am going to mount a DD BIX to the back of my case using a gutted 120mm fan, I am thinking about building a box inside using plexi so that air can be drawn from a 60mm hole in the top and a 80mm hole in the upper corner of the side panel. For air flow throughout I am going to mount a 92mm fan on the left side window and possibly a few 60mm fans on the right side down low. I am also debating mounting an 80mm fan in the front like Massive installed in his case. I am wondering if anyone has thought about this or perhaps has a system assembled and can tell me if the fans will fit.
