The directions are in the motherboard manual. You have to remove 2 or 3 jumpers on the front panel audio connector, consisting of about 9-10 pins, located next to the onboard sound ports. Make a note of the pin positions. If you change cases or sell the board to someone else, the speakers won't work with the pins removed. The connections are pretty straightforward. One wire from the case is unnecessary, so just leave it disconnected.
