Having done a bit more research, I found that this is one of the NUC family, Intel call “formerly Dawson Canyon” see: https://ark.intel.com/products/codename/126293/Dawson-Canyon
I also notice also that @Danny Dulai had successfully tested another of this series a couple of weeks ago; the NUC7i7DNH see: New Dawson Canyon NUCS supported? Other fan-less NUCS support? [yes on Dawson Canyon]
So although not a guarantee that it will work. It gives me hope. The NUC7i5DNKE can be found at low prices and will also fit nicely in the Akasa fanless case.
Anybody have any comments on this?
