No you can't do it since there's not enough space unless you get really thin fans. And if you are going to mount that you might as well get 140mm or 120mm quiet fans to do the pulling. And if you can get your hands on H80, H80i, Antec Kuhler 920 or Zalman LQ320 then do that and mount it on the rear exhaust fan. There's very neglible difference between those 4 I just mentioned compared to H100 in performance and you save money too. Cheers!
