Open to suggestions on what to do with these.

I have 5 HP Elitedesk 800 G4 Miini PCs Each has: Intel i5 8500T 16gb DDR4 512gb m.2

I'm leaning towards proxmox clustering them. I want to have a few game servers running, plex and home assistant. I have a NAS already running with 36TB of media stored.

What else should I do with these or are there any scripts that you'd recommend for me? I'm new to home labbing so please go easy on me.

Can't wait to post pictures of the lab when set up.
