I mean it would work, but depends on the load, it can definitely host some website, be used as a backup server or something. I installed a modern version of proxmox and even plain debian on it, so it would definitely work. But performance would be poor for heavy task like a game server.

As for the consistency itself, the server would run 24/7 without an issue, and it’s still built like a tank and it has been made to be resilient!
