Machine to run Frigate NVR

At the moment I've got frigate running on an old dell server through proxmox, writing to drives on that server, but they are shared with a lot of other services.

I'd like to separate it and have a machine that is kinda just acting as a full NVR and writing to it's own drives.

Anybody have any suggestions for one? Are the mini PC's any good or I guess they wouldn't hold enough drives to have plenty of storage.
