re: PLEX Servers

Oh man selfhosting (if you're into such things) is good stuff. I often call it my digital ant farm. Half of the fun is setting it up and tinkering with it. The benefit of this hobby is that you get functional and useful services as an output. Look into proxmox. In layman's terms its a way to split your hardware into multiple servers so you can do multiple different things. In technical terms it's a free and open source hypervisor you can spin up VMs and containers and also easily join multiple computers together so you can move those VMs around. My "main" box is basically an old desktop computer, but its probably at least 8yo. The other two nodes in my cluster are little tiny micro pcs I basically saved from a trash bin. If you're careful with your resource allocation you can do a lot with old hardware.
