N100 is a good low power CPU (I own one) but beware that they only have 9 PCIe lanes. Every peripheral and motherboard slot needs at least one lane and many (like NVME slots) often have more. For example, NVME normally uses 4 lanes and each NIC needs one.

So, do the math, 2 standard NVME slots and a NIC use all your lanes so there would be none for the PCIe slots.

The Asrock N100m tries to deal with this but limiting the number of lanes per device but it does so, potentially, at the expense of performance. It assigns 2 lanes to the NVME slot and it's 16 lane PCIe slot only wires 2 of those lanes. Shit should still work, but it may not be at its fullest performance.

Anyhow, beware that striving for lowest idle power may have other hidden costs if you also want flexible and high speed I/O.

I use Traefik and Oauth to implement two-factor authentication with single sign-on via Google. Works fine if you don't mind the requirement that all your users must have a gmail account with Google.

How would that work with a Jellyfin client running on a device like a Chromecast dongle? The code on the dongle doesn't (IMHO) know how to log into an SSO service.
