I have searched around and have not found any luck in finding what coolers will fit in this thing. As big as it is it should fit about anything but I have not found anything concrete. Mainly I am looking to pair a Asus P5E-VM HDMI with a Q9450 when they drop and top it off with a 120 Extreme if it will fit. I have a lead on a good deal for a 120 but need to know if it will fit before I get it.
