Chord Electronics 2GO Roon endpoint "and Server"

[BlackJack]

ODroid H2 seems to be an SBC who might be able to serve you for that. @Jacques_Distler appears to have one running with success.

Roon Core on an Intel based SBC?

Runs Roon Core very nicely. (I strongly recommend spending a few extra $ to get dual-channel RAM.) If you’re interested, buy one before they run out of stock (I think they’ve been out-of-stock for the vast majority of the time they’ve been nominally in production).

I don’t know if there are pre-assembled builds available though.
