I recently bought a relatively cheap itx motherboard. As a consequence there's only 1 9pin USB 2 and 1 20pin USB 3 connector on the motherboard and my case has 3 front panel USB's (2 x USB 3 and 1x USB 2). Now I don't want to leave one of these unplugged or unusable. I've heard of PCIE cards that add more connectors to the motherboard but my only PCIE slot is occupied by a graphics card. Does anybody have any other suggestions on how to add 1 20pin connector to the motherboard?? Thanks in advance
