Unfortunately, like I said, you lose the top if you aren't using only the rear exhaust man, which then, in my opinion, is not enough, because if you're running high end hardware with the amount of heat that's gonna be generated in the chassis, even if you're running a Rh colors 1 140 millimeter fan, that's a lot of heat to have to exhaust, so you don't have to run it at a higher rpm to kind of match the amount of fans pushing air in, which then means that you're gonna be dealing with a ton of positive pressure air coming out of all the cracks and then only one fan having the responsibility of exhausting the heat, which I think is substandard.
