I'm currently designing a new high end case that I hope to make commecially availible. I was wondering how many fans you think a high end case should have. As it stands the deisgn has four 120mm fans plus whatever you have in your psu. Does that sound like a good number? excesive? too little? I can honestly fit at least another 120mm and two 92mm fans in addition to these, but that might be too much. I was thinking that having only 4 fans would allow you to easily control everything with just one of those fan controllers that fit into a 5.25" bay. Thanks.
