You could create a NASpi! Check it on YouTube

PiHole, Jellyseerr, Radarr, Sonarr, Emby, Syncthing, Homepage, Home Assistant, and Snipe-IT.

PiHole is self explanatory.

Jellyseerr, Radarr, Sonarr, Syncthing and Emby are used for media management and streaming, alongside a remote seedbox.

Homepage is a locally hosted browser landing page with widgets for network monitoring.

Home Assistant for locally hosted home automation controls.

Snipe-IT for asset management. Way overkill for a home user, but it’s free to self-host. Make sure all my assets are listed, can upload receipts, photos warranty info, manufacturer info, etc. so it’s a single place to find all of that information if I ever need it.

Please don’t go the RaspberryPi route for serious self-hosting, you’ll regret it later when you’ll realize it’s not powerful enough for ie NextCloud. It can handle PiHole for example (minus digging through the historical logs / stats via its interface), but when adding more and more services (Nextcloud, Jellyfin, a VPN, home automation, etc), it will be easier to expand via VMs (Proxmox) / Docker on a single machine that you need to maintain, you’d have easier snapshot backups, single point for firewall rules, etc, than adding RPIs. Buy a mini server, you’ll have flexibility, room for upgrade, and the costs and power consumption will be justified when scaling to multiple services.
