Looking for a mini PC for Proxmox Backup Server

I run Proxmox on a DeskMini H470 and want to run Proxmox Backup Server (PBS) on a separate piece of hardware. I know I can run it in a VM or on the Proxmox host, but I'd prefer a separate machine.

Is anyone running PBS on a mini PC? I have gigabit networking, and the total disk of all my VMs/LXCs is about 200GB. I would like to throw 2TB SSD into one of these and be done. Thoughts?
