I was looking for something just like this, A small, battery powered system with an integrated display. Started my search for a pi case but quickly realized an N100 x86 device with higher specs than a pi can be purchased for significantly cheaper. let’s just hope I can get Debian on it.

Honest question, I’d love to host email but it seems like a huge pain in the ass these days with trying to keep from being delisted. Is there a decent, home user accessible email system that’s useable out there?

A decade ago it was easy and doable but even in professional life I don’t deal with email backend anymore, all google or o365.
