I haven’t been following hardware for a while, granted, but this is the first time I see a desktop build with an arm64 cpu. Didn’t know you can just… buy one.
For what it's worth, I've been using a Lenovo X13s for some 3 months now. It's not a desktop, and it took years for core components to be supported in mainline Linux, but I do use it as a daily driver now. The only thing that's still not working is the webcam.
