if you look near where you plugged the regular power switch etc there should be a yellow(normally) usb header 9 pins 1 row of 4 1 of 5 normally they run power - + ground in that order the ground near the end with the spare pin.As far as audio i wouldnt use them and if theres firewire you need a header for this too these should be highlighted in your manual

Im not sure but looking at the pic of your mobo some of these headers are not present with a bit of luck you should be ok lol

edit the usb header appears to be next to your first pci slot thats if you went with the asus and there blue lol lol

The other wires all ie switches ide active and power led are all 2 core plus minus normally asus boards are marked and the +pin so you cant go wrong if you use a magnifying glass or squint lol you will see the board is marked as to what goes where lol lol
