The other consideration is whether to go ROON ROCK or full Windows 10 PC.
The NUC/Windows approach seems to solve so many problems and provides so much more utility.
While Roon ROCK is great for use on a NUC, it won’t be any good in the Control:15 as you’ll just have a black Roon Core screen, there’s no ‘Control’ functionality in ROCK. If that’s all you want, the existing hardware can do it, and run Roon Bridge for an output as well. I’ve done all of that already on the existing Control:10 hardware.
If you want control functionality, you’re pretty much stuck with Windows. The only other alternative is to get an Android o/s running on it, which seems to be fraught with dramas as far as I can see.
The existing hardware can run Windows, but can’t do OpenGL 3. A NUC can do OpenGL 3, but doesn’t have an LVDS output for the screen.
Solve either of those issues and you’re away!
Cheers,
Jason.
