I have a Pi3 running pihole/dhcp for my home network, and 4 Pis as part of my home k3s cluster (along with 3 cheapo nucs). Yes it's overkill but I'm in infra and I learn a lot from it. The cluster runs nextcloud, collabora, plex, longhorn storage, deluge, nzbget, some custom projects I built to sync my bank accounts with my finance software and to sync photos from Signal chats to my nixplay frames, backups for my NAS, Grafana/Prometheus/Loki, netdata, etc. I also run an entertainment company and we use a Pi Zero to control our onstage LED lights via presentation remote or wifi as a fallback. I keep thinking of other things to do with them, but this is already enough to maintain in my "spare time".
