Depends what you're hosting on it. Plex yes and no, RPI doesn't transcode well, that Lenovo should be ok to a degree.
Again depends what you want to do. I've got an one of these https://www.bee-link.com/u59-pro-n5105 that I use Proxmox on, Plex, Sonarr, Radarr, Prowlarr in LXC and Windows for various shitty programs that aren't on Linux… It does the job.
