Why so many fans? If you add too many you will strain the power supply. Might want to try water cooling or get a higher wattage powersupply.

I had a PC that had 13 fans. They all ran off one molex connection but I built a special circut board for all of the fans to connect to and also had a fan controler installed.

You can always make the fans run at +5V too you know. May not be much in CFMs but it gets the job done.
