Intel NUC7CJYH still viable?

Thank for the reply. I do have a couple quick questions for you:

Do you run Plex in its own VM or are you running the Plex addon inside HAos?

Do you run TrueNAS or another NAS software?

How much internal drive space does the NAS, Plex HAos and everything else take up?

My NUC7CJYH comes with a 120 SSD but I am wondering if that is enough or should I order a larger one?

I will definitely be going the Proxmox route but it looks like there are two ways to install it, one via KVM/Proxmox and the other Using This Guide

So which is the best way to go?
