Stability-focused no-frills board with the feature set I was looking for.
Taking off one egg because the following situation is not clearly addressed by MSI: Once assembled board would not post. My first guess was it needed a bios update since Ryzen is known to be picky with regards to memory. But how can you flash the bios if i you can't get into it? Thankfully this board features a bios flash button on the back panel. Follow the instructions from MSI to use this feature. In summary: download latest bios from MSI, rename bios file to MSI.ROM and drop it in the root of a FAT32-formatted flash drive. With the computer POWERED OFF, put the flash drive into the lower usb port and push the flash bios button. A red LED will begin blinking indicating the bios is being updated. Once the update is complete the LED will turn off. After I did this the board posted and I was able to move onto installing the OS. Hope this helps anyone who is in the same situation.
Of course only time will tell but out of the gate this board appears to be a solid choice for no-frills micro atx builds focused mainly on stability and longevity.

Everything about this motherboard is good, except for the fact that the bios flashback for zen 3 didn't work(Ryzen 5 5600x). I tried with multiple different drives multiple times, followed countless guides, made sure it was "MSI.ROM", show file extension names, MBR Fat32, low capacity drive, etc etc, but nothing worked. I bought a B550 Gaming Carbon Wifi, and it flashed first try, and I also saw on reddit that many others were experiencing similar issues, so if it isn't working for you, I would recommend you return it and get a new board.
