@SonoMichele My biggest 2020 project was actually running a public Nextcloud instance on my home network. It was a non-trivial investment of time and money but it was also very fun.
I ended up installing IPFire on a used HP Elitedesk 705 G3 SFF (~ $120) and using that as my router so I could easily setup a proper DMZ network. I also bought a decent 2-port ethernet card, which added about $60.
I then installed Nextcloud on a Raspberry PI 4 (~ $80 total) in my DMZ network and it's worked very well for me.
