I'll freely admit to skimming a bit but yes proxmox can run trunas inside of it. Proxmox is powerful but might be a little frustrating to learn at first. For example by default proxmox expects to use the boot drive for itself and it's not immediately clear how to change that to use that disk for other things.
The noctua dh-15 is overkill for that cpu btw unless you're doing an overclock which I wouldn't recommend for server use. What's your plans for the 1060? If using proxmox you'll want to get one of the "G" series AMD CPUs do that proxmox binds to the apu and then you should be able to do gpu passthrough on the 1060.
