I have the above motherboard and noticed it has a USB3 header. The board only has 2 USB3 ports so was wondering if it was possible to get a plate that goes in one of the expansion port holes at back to give me extra USB3 using the header. I do a similar thing for eSATA. Had a look and cat find any, do they exist? Would not mind having an external box tyoe thing with USB3 ports that goes through a hole in back of case.
