I have a framework 13. Bought it with 12th gen intel mainboard, upgraded it to AMD when that came out. Also upgraded the battery, RAM, and soon the screen when the 120hz one ships. It’s super easy to get into, just five screws and then pop the trackpad/keyboard cable off. I honestly love it.
Framework has fantastic support for windows and Linux. There used to be some minor fixes needed on certain models but they’ve since resolved them and my experience on Fedora and Arch have been plug and play. On windows they have a driver install script that installs everything in one go, that’s nice too. And yes Minecraft does run on Linux, at least the Java version does. Idk about bedrock though
