Alot of us who have a Raspberry Pi 3 or 4 might upgrade to the Raspberry Pi 5.

Doing so would leave us with 2 Pi’s. What are some great use cases for the older Pi, that would no longer be the main machine?

What do you use the Pi for now?

I had a bunch of Pi 3Bs sitting around, so I made piholes for a few friends and family, I made a dedicated MAME emulator that I never have time to play, and I gave one to each of my kids to learn about computers and linux. I also use one for work as a linux test environment for our software, but the 3 hardware doesn’t really keep up.

Right now I use it for:

  • PiHole
  • Plex/Jellyfin
  • WireGuard VPN
  • Sonarr/Radarr and all that follows.

I would consider giving it away to family for the same purpose. Thanks for the suggestion!

Since none of these require a Raspberry Pi to run, I would suggest using a mini PC (with an Intel N100 or similar) instead of a Pi 5. With all the accessories needed for the Pi, a mini PC can actually be cheaper and of course a lot more powerful. Since the Pi 5 is very power-inefficient, a mini PC can even be better in that regard too if that matters to you.

Especially for Jellyfin a PC with an Intel CPU with integrated GPU is awesome, since Jellyfin supports hardware transcoding with that.
