Small motherboard that does the job. There are only 2 ram slots, but that's enough for me. USB-C for the front panel, USB 3.0, 2 M.2 ports, one of which is 4.0, it's still very comfortable. And for those who want RGB for extra performance, it's got what it takes.
Not disappointed, thanks LDLC.
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.
