Please take the 120mm fan off the back and put it on the top where it won't be seen bc it's ugly lol

Put the Cooler Master 120mm fan on the back, and the CM 140mm fans on the front. You can do away with the red 120mm fan if you want, it really doesn't fit in with the rest of the build and I'd like you to have positive air pressure so you don't collect a lot of dust.

The fan that you put up top, put it towards the rear. Leave the front fan mount up top empty. Heat will still make its way out of the hole.

When hooking up your fans, connect the two 140mm fans to one splitter and connect that splitter to Chassis Fan 1 on the motherboard. This will be your intake. Connect the two 140mm fans to the other splitter and connect that splitter to Chassis Fan 2 on the motherboard. This will be your exhaust.

Separating intake and exhaust on two separate splitters helps you to control airflow and air pressure via fan control in BIOS because one button will be intake and the other will be exhaust.

Of course, the two fans on the CPU cooler should go to CPU_FAN and CPU_OPT on the motherboard.

If you really want your system to be silent, these anti vibration mounts will keep the HDD mounts nice and silent. http://www.frozencpu.com/products/6138/scr-116/SilenX_Rubber_HD_Mount_Screws_-_4_pack_IXA-GM4.html?tl=g33c113&id=mF6bBdyz I don't view HDD silencing parts as being necessary though. Your decision.
