Simple question really...
Can both of the case USB header sockets be used together, or are they mutually exclusive?
My case uses the USB 3.0 header, so I want to make use of the USB 3.1 header to add an additional USB-C port to the rear, via a suitable cable plus back-plate. I have found such a USB 3.1 mobo cable with USB-C back-plate listed on eBay.
