I'm newish to building computers and just put together a new one. To keep things simple, I have an Antec 900 case and a ASUS M5A97 motherboard. I cant seem to figure out a way to connect/use the USB ports in the front (on top actually) of the case (the ones near the power button). Is there anyone I am over looking or can I purchase something extra that will allow me to utilize the front USB ports?
