once you get Unraid going for storage, check out Syncloud (https://syncloud.org) for the app side. I made it so im biased but its open source. it handles Nextcloud, Jellyfin, Bitwarden etc with one click installs and automatic https and auth. I run it on a separate Raspberry Pi alongside my main storage box so each does what its best at. nice way to add services without overloading your Unraid setup with docker containers
