I’ve got a few

1. Pi 4 with a 1tb SSD for my proxmox backups
2. Octopi for 3d printer
3. One running as a Spotify connect client for some “dumb” bose speakers in the lounge

If you can get your hands on one, a Raspberry Pi Zero 2 W with the official Pi Camera Module 3 is a great solution but it lacks the ESPHome integration.
