AMD Ryzen Mini-STX: ASRock’s DeskMini A300

The front panel ports are the usual DeskMini affair, being a microphone input, headphone output, USB3.1 Gen 1 Type-A and USB3.1 Gen 1 Type-C. To the right, the standard STX form factor front I/O, embedded into the board, and to the top, the VRM section powering the CPU/GPU combination in the AMD APU. On the rear of the board, a giant AMD backplate, the CMOS battery,  the twin SATA power/data plugs, another NVMe-only Ultra M.2 slot, and a bunch of supporting circuitry, including a Realtek ALC233 chip for the front audio.
