I've been using the Beelink SER5 with Manjaro Linux since a month. It also comes preinstalled with Linux, but I got the Windows version. Runs smooth and perfect, no issues at all except for WIFI after suspend that had a small patch. Definitely recommend it. Much better than a laptop since portability isn't the main goal as I prefer a big monitor and use it as a daily use PC. For around $400, glad to have this little beast with 32GB RAM and Ryzen 5600H.

Beats buying a laptop for double the price and likely worse linux compatibility.
