hello, i just bought a new case with all the goodies like blue leds and led fans, etc......i had an old motherboard lying around and i was wondering what all i needed to put on it just to make the case power up....does it need the battery? or a processer? right now its JUST the motherboard, and the powersupply is powering up when its plugged into the motherbaord. So what do i need to add for it to work? or should it be working now?
