Depends on the Pi in terms of how much you can do, but yes.

I have a Pi 5, and I’m running Pi Hole, Nginx porxy manager, Jellyfin, Syncthing, Paperless NGX, and a full servarr stack (including Qbittorrent and a VPN). No issues; 4.6 gb out of 7.9gb ram in use, and no appreciable bottlenecks.

I would just caution that things like Jellyfin are a moveable feast - I am 1 user streaming content on my own to 1 device without issues at 4k. But more simultaneous users and if you start depending on transcoding your mileage may vary. So yes Jellyfin and other services will run fine, but any server can be put under pressure if it’s not adequate for the actual usage.

Its an interesting build and cool, but this seems overpowered and overspecced to me?

From his reddit post he’s hosting: Immich, Nextcloud (file sync across all devices), Frigate NVR (Coral AI detection + Home Assistant integration), Plex (with full *arr stack), pfSense (firewall, DNS, DHCP, WireGuard VPN, ntopng monitoring), Vaultwarden and Pfblocker. He says on the Youtube video: Plex, Home Assistant, Pi-hole, Immich, Nextcloud, Frigate, and more.

Does this really needs 4 Lenovo PCs (1 used as the router) to run all this? Maybe he has multiple users and is going hard on the Immich and the security camera set up (including video processing?). Even then I just can’t see how this would make full use of all this hardware?
