Please report back which model you end up with from your Amazon purchase from seller “Protech365”. I did see that listing on Amazon but they are charging quite a premium for it at $738.85. The “N” version I just purchased for $597.99.
It looks like the tell-tale way to see if you have a NUC10 that supports HD Audio (and as a result, supports being a Roon zone) is the headphone jack on the front panel.
The latest NUC generation, NUC 11 (which is selling for $629, though backordered currently), does have the headphone jack on the front panel so if we can get Roon ROCK compatibility with that model, it would be a compelling choice. I know there an issue with not having Legacy Boot Support on the NUC11 that has been an obstacle based on other threads on this forum and NUC11 runs hot (if I am reading this post right Nucleus moving to Intel NUC11?)
