Getting started

I am currently living in a rental and use a Synology NAS for photo storage (I am a photographer),and have an old gaming rig to get started. I want to run a plex/jellyfin server, (still deciding) a few gameservers as well as a couple of VMs to act as a sandbox. I am looking for ideas for what to install on the old gaming rig to get started? Should I look into hypervisors or just run things in docker on a Linux distro. Is it worth running the media server on the NAS or should I put it on the "server" to and connect the NAS for media storage?
