Thanks for the quick answers guys, fan controllers is actually a great idea to feed the fans!
How do i go on about plugging all the cases front pannel to turn them on and off? and I dont really want to make the USB ports functionnal, I dont really care about that, I just want fans to spin and LED's/RGB fans to be turned on, and the power to turn on and off the systemes. I can sacrifice the luxury to turn them on/off if that is an issue.
Anyone knows what kind of splitters I need to plug Case Front IO to a PSU ? Such as the PowerLED +/-, Reset, Power, and HDD LED?
