My motherboard has USB 3.0 on it's back panel. However it is tucked away under my desk so it's a pain to simply move files back and forth from a flash drive.
Yep - thats what the link above does. If you look around newegg you will see there are lots of different options to ad a front panel USB 3.0. You could pull the cables out of the metal box and put them into the appropriate holes on your case if you wanted to.
