That’s what I’m using: I can try to answer some questions but note that I haven’t done any power consumption measurements nor have I tried to minimise any consumption (disc spin-down for example). Look at my NAS details for fractionally more info.
You are using an Intel-based Gen. 8 machine with the Xeon CPU. I am sure this one works well. This may be my alternative.
For now, I was wondering about the low-power AMD Apu they build the Gen.10 models with.
