you must have the 900 case with "upgraded 3.0" for front ports. If that's the case, get a PCI card with header that matches the case connector and you'll be fine. Some people stretch a long cable through the back and plug into the rear ports which looks tacky, and then you use up the rear ports....With the add-on card, you can get 4 USB 3.0 ports.
Awesome! Thank you so much!
