Secondhand macbook pro with the M2 chip and as much memory / hdd available ; it is said to avoid 8g of ram, I went with 16.
Slap Asahi on it, the latest version plays games quite nicely - and since Asahi is dual-boot anyway, you can try the macos side if something fails.
(Currently Asahi doesn’t support m3 or m4 chips. M2 machines should be available at bargain prices, mine new was €1500)







While mint is neat, Ubuntu or any distro with gnome would work in the “very graphical, large icons” sense.
I dont know about mint, but debian does security updates automatically and just politely asks for a reboot now and then, perfect for an “unattended” device.
