We have been considering doing something like this exact thing as a Intel NUC base, but we can’t seem to figure out how to make it worth our time for less than $1000 retail. That would be for the box you mentioned above completely plug and play ready to go software/updates/etc… We’d even make it fanless. You’d still need a Roon license to use Roon on it.
We’d build the box in such a way that if you wanted to throw away the Roon software on it, and just repurpose the machine, you could.
I’m not sure there is interest in this at that price point… feedback?
