I still use all 3, though I’m slowly moving CPU intensive containers to the NUC. The Pi is untouched so far, partly because having edge services there will make it easier of I decide to implement a DMZ.

The NUC+Proxmox is a great combination. Bit of a learning curve (eg. as with Docker, you need to pass devices in Proxmox and then to the container; same with CIFS shares), but there are lots of resources out there. I have no regrets going this route, and it had low power consumption.

On Windows thing, I was specifically referring to the server OS as the NUC came with Win11. Do whatever works for your desktop/gaming setup.

Though I also switched that to Linux (EndeavourOS, though there are other game-friendly options) a couple of years ago, and its worked out great. Guild Wars 2 was my most modded Windows game, and I can run all except one of the Windows-based addons I want for it. Setting it all up the first time is a ball ache (as it was with Windows, but that was done over time 🤷‍♂️). 😊
