I'm definitely fascinated by the fact that a number of Ryzen-based mini PCs are coming out, and this one's no exception. The tool-less case is definitely a bonus.
Of course, being new, they probably have to start with a medium/medium-high spec machine (relative to the size and power constraints). Because of my obsession with putting together my Micro Machine (see sig) a while back when the ASRock A300W came out, finding more of these, that may compete with even my ultra-cheap price of putting it together, is fascinating.
I hope that this takes off well enough that they can make, say, Ryzen 3 or even Athlon versions at lower price points. I know, I keep looking at these and thinking "Could this have been my Micro Machine if the A300W wasn't the only option I had available at the time?"
I do think the single-8GB stick is an odd choice... though maybe it's about giving the option to upgrade easily to 16GB later by adding an (identical) 8GB stick?
