I’ve been running an n100 box as my main everything box for about 1.5 years. I capture metrics on it and can say the thing is nowhere near capacity. This box is running jellyfin, a dozen or so nfs mounts that are heavily utilized, a dozen or so lightly used samba mounts, grafana, prometheus, jenkins, and a handful of mysql instances. I maxed out the ram (32gb) from the start and it averages 8gb usage, and has never exceeded 10gb. Historically, the CPU usage averages 28% utilization. I think as long as the board has nvme storage you’ll not feel constrained by these little hosts for many years.
