it isn't that hard, if u take usb cable and cut it , there are 4 wires, red, white, green, and white.
take a usb cable and cut it
like...this bad illistration is a male plug and the wire ----------
then there should be wires going from the usb on the front of them comp, take one, and cut it, it should have 4 wires on the inside of that. same colors, take the male usb cable and strip the wires and connect them to the wires from the usb cable from the front.
know what i am saying? connect em all, and then electrical tape em, and plug the male one into the pci slot usb connector.
or screw that, and just get a pci card and a couple of these.
