Curious to know what the experiences are for those who are sticking to bare metal. Would like to better understand what keeps such admins from migrating to containers, Docker, Podman, Virtual Machines, etc. What keeps you on bare metal in 2025?

Wow, thanks so much for the detailed rundown of your setup, I really appreciate it! That's given me a lot to think about.

One area that took me by surprise a little bit with the HBA/SAS drive approach I've taken (and it sounds like you're considering) is the power draw. I just built my new server PC (i5-8500T, 64GB RAM, Adaptec HBA + 8x 6TB 12GB SAS drives) and initial tests show on its own it idles at ~150W.

I'm fairly sure most of that is the HBA and drives, though I need to do a little more testing. That's higher than I was expecting, especially since my entire previous setup (Synology 4-bay NAS + 4x SATA drives, external 8TB drive, Raspberry Pi, switch, Mikrotik router, UPS) idles at around 80W!

I'm wondering if it may have been overkill going for the SAS drives, and a proxmox cluster of lower spec machines might have been more efficient.

Food for thought anyway... I can tell this will be a setup I'm constantly tinkering with.
