Step 9: Wiring the Front Panel Buttons, USB and Audio
Cases usually have 2 buttons (Power and Reset) and 2 LEDs (Power and HDD). Looking in the motherboards manual you should be able to tell where the wires leading from the buttons and LEDs go. The colored wire is usually the positive and the white or black wire is usually the negative.
Most cases usually have a headphone and a microphone jack in the front also. This is called the AC'97 panel. You should be able to find instructions on where the wires go in the manual. There is a wiring map below for the standard AC'97 panel. Newer motherboards will sometimes list this as Front Audio and HD Audio too.
Cases generally have USB on the front too. This one is easy. The motherboard will have 2 places for it to fit. There is only one way for it to fit, and it doesn't matter which one. Check the manual if you can't find it.
The system speaker should be somewhere near the buttons and LEDs. This is not required for any real opperation, except telling you that something is messed up in your computer.
