F_AUDIO, F_USB2, F_USB3 Interfaces
Below is an example of a standard PC case front panel USB and audio expansion board, which includes Audio, USB2.0, and USB3.0 interfaces. You can use the corresponding connectors on the Megrez motherboard to extend USB and audio interfaces to the front panel of the PC case.
The Megrez motherboard already has onboard Audio, USB2.0, and USB3.0 interfaces, so the corresponding functions can be used without a PC case.
