The OP asked about running Roon core on a Mini, I’m telling him of my experience.
Do you run Roon core on a Mini?
- Can’t run Roon core and anything else simultaneously, i.e Time Machine etc., without impacting Roon core.
- Can’t reliably use DSP or upsampling.
A lowly i3 NUC, which is what I switched to, had no problem with either of these things.
I think people pick a Mini over a NUC because they think it looks like a media machine or they have already bought into the Apple eco-system.
