RAS under Linux, it works well. I used a Proc Ryzen 5 4600G and there are problems with the graphics card under Linux, see the product review.
For the moment I'm not using the usb-c on the front panel, but that will probably come later. It's an asset
A branded motherboard for long-term use and with a USB C connector for the future.
