Thanks! Was mainly wondering after I saw the Optimum Tech review of the H2O, but now that you mention it, the second USB Connector on the B660-I and Z690-I is an old 19 pin connector (and while I personally would find 1 USB-C + 1 USB-A port on the front useful, it would probably compromise the clean look of the case).The internal USB-C Key-A header does only support one USB-C. The old 19pin header has no real USB-C support. Without a controler board one port is max.
