I wouldn’t call N series “dinky”. N100 runs my daily device, coincidently surface-like tablet Chuwi Hi 10 Max, and three of my homelab servers. Proccessing power is more than enough to run modern desktop distro, all the todays shitty javascript websites, work in IDEs, virtualize, and all others server-side task I throw at them.

I’m in the same boat, so I had set up Syncthing more like centralised service - installed one instance on my home server, and made every other device sync only with it. Files propagates without issues.
