I use one of these. For a system that’s honestly mostly idle, it’s plenty for proxmox with Plex and pihole and whatever else, and it’s good on power and heat and noise.

I made the mistake of getting Seagate 10TB rock tumblers, but they’re the only source of real noise. WD would probably have been quieter.

I have this and my switches and a ham radio base station all racked up on top of the cabinets in my laundry/utility room, out of the way but not hidden away, so I can still notice if the fans are too loud or the wrong lights are blinking or not blinking or there’s weird smells etc.
