The lack of a RJ45 network connection into the SP3 could pose a problem for using it as a Server... the same would be true for any Roon Server that doesn't used a cabled ethernet connection.

The USB3 to Ethernet Adaptor might be a good investment if you plan to use the SP3 in the Roon Server role on a permanent basis serving a number of remote clients.

In the meantime, the SP3 can certainly be used for trial purposes to see how you like the Roon UI.
