You can now run Coreboot on the MSI PRO Z690-A WiFi. This is kind of a big deal because if you wanted to run a system with even a semi open BIOS like Coreboot then you were usually limited to laptop parts or older desktop parts which for gaming is a tough sell for those who want higher resolutions; higher refresh rates and higher settings.

Even better news is that you will be able to buy a pre Corebooted board for those who aren't comfortable flashing it themselves. It's on back order but will be there soon.

Pair this with a 12th gen CPU and a good GPU and you have yourself a high end gaming system that is also better for privacy and security than anything else I can think of.
