ASRock DeskMini A300 Barebone Kit - Junk

The case is an X300, but the internals are an A300.
It was booting up until just now.
I installed beta version 3.70E of the BIOS.
It was operated with a 5000-series CPU.

Reasons for being junk:
For some reason, the wireless LAN is unstable.
A CPU not officially supported by the beta BIOS was used.
BIOS settings cannot be changed.
Sleep mode is not possible.

This is a barebone kit.
CPU, memory, storage, etc. are not included.

For usage, I housed the motherboard inside a GameCube.
I used an X300 case that I purchased used.
