I'm considering either:

GMKtec NucBox G9

Or

Zima Board 2 1664

I want something that's easy to use. Zima seems ready to plug and go almost, which is the huge plus, but the huge down side for me is cost - not only does it cost more, but I'd have to pay an additional 25.5% VAT on top to ship to Finland.

The GMKtec comes with Ubuntu at least (I'll be deleting Win11), but I don't know how Linux support for it is outside of Ubuntu. I'd prefer something easier to run like CasaOS or Yunohost (not sure which is more beginner friendly). Also don't know if those run Waydroid, since I'm pretty sure Ubuntu does (want to use S-tube on TV).

What do y'all recommend?
