Wipelnard,
I confirm that Raspberry Pi 4 and Ubuntu 20.04 (desktop version) is amazing. So amazing, that I'm going to adopt it as a "Observatory main PC" !
You know what ? I did choose this setup first because it has a dual HDMI port - and I've two large screens on my desk. It works perfectly - just incredible.
(note : I use t 4Gb version).

Also : I'll work in client - server mode, and the Indi server is in another Raspberry-like module, close to the telescope.

Regards,

François
