I have this case and like it. I have an Enermax 430W p/s with its two fans, two more fans installed on the back panel in the stock positions, one below the p/s and one above, and I installed two additional fans (80mm) in the top of the case. All of the added fans are exhausting the case, so the airflow is in through the openings in the bottom front and the slots that run vertically up the fronts of the side panels, then toward the back and top of the case where it is all exhausted.
