Everything's great, but the mobo doesn't have a header for the 20pin USUB 3.0 for the case.
I'm finding two routes, neither of which I've seen conclusions to:
1) Get an adapter to route the two USB 3.0 external ports on the back of the case, through the case, to the front ports
2) Get a 20pin male to 20pin male adapter, attach to a 20pin female to dual USB 3.0 Ports, and from there using 2 USB 2.0 to 5pin connectors
i have seen people cable out the back to rear usb ports and connect them up to the front. as long as all the cables mesh up i dont see why it wouldnt work. you do lose the rear ports though. you could always just use a usb extension cable (fem to male cable really....) and run that along the side of your pc from the rear ports.
you should be able to adapt 3.0 header from the case to a 2.0 mb. i've never done this before but it should be possible. it might even be as simple as letting the extra headers stick out not attached to anything on the plug. read the manuals. if you do need adapters its easy to hide wires. you would just tuck them up near the front panel ports.
