I am building a new PC and brought the Gigabyte Z790 Gaming X AX MotherBoard. However I hadn't noticed that it only has only two inputs for jack on the back. I read in its manual that you connect the 3rd jack "on the front panel" but I cannot understand how that works or what exactly that means. Fortunately, I am not building the PC by myself, but I'd like to know this info before I start the setup just in case this MoBo doesn't suit my need eventually. Thanks.
