No, because you ahve one SERIOUS problem - your approach does not scale. As in: NOT AT ALL
As in: You can not put one above the other.
Rather go for something less high, longer, with fans on beginning and end. I o that. The idea is that the case is 20cm high, fits into 5 rack units and uses either 2x20cm or 3x16cm fans on both sides (4 or 6 fans) to move the air through as fast as possible.
