How long is a piece of string?

Yes.

Xmpp, irc, email and websites are all pretty small in terms of resource usage. Where you’ll have problems are with heavy compute workloads like 3d rendering, AI, 3d gaming (sorry, no crysis), and crypto mining. They all can be done on a rpi but not done well.

Slaps board of Pi this bad boy can fit so much fucking dust in it.

i run homeassistant, pihole, 2 projects of mine using NodeJS, nextcloud, a very simple static website and Nginx for some DNS customization like pointing nc.home to a specific port. My pi is a 4GB one and for now the used RAM is not even 1 GB. I run debian with no graphical interface

It can do at least three calculations per second.

I serve several TB of Video movies, TV and music around the house. Jellyfin rocks.

That he can do, indeed. Maybe even some pornhub too 😁

Is capable of seven

Since I tried zimaboard I would never go back to RPI, personal preference I know but I love it.

I love this distro

To be fair I my 8vcpu vm struggles with transcoding, so I wouldn’t hold that against the pi. I got a little beelink box for jellyfin and it transcodes no issue with quicksync

NEVER transcode. Do it as a background task offline. Even GPUs and desktop servers are best offline.

Pi 5 is out very soon.

There are a lot of factors that go into whether a big server like Google will accept your email, it’s so much work that it isn’t worth it unless you really have to. Just “self host” on proton mail or something

And even if they can get around the port 25 block Gmail and other large email providers often block any emails coming in from a residential IP.
