Need help making front USB work on rebuilt system.

For reason beyond my control with the choice of the case, I'm putting an ASUS ATX Motherboard into an HP Pavilion 750n case. The motherboard has four usb2 and two usb3 ports on the back. This is fine, however, the person I'm doing this for wants the two usb ports on the front of the case to be functional as well. What's the best way of going about doing that? Thanks ahead of time.

 

There should be headers right on the mainboard; just double-check that the pins match up.
