Hi Kian,
Yes, I think a remote desktop app that allows access to the file system on the NUC would be exactly the same as an RDP PC.
I’m using a BRIX S GB-BXi7H-4500u which has a dual core Haswell (4th generation) processor (1.8/3.0 Ghz) with 8Gb RAM. The OS (Server 2012r2) and RoonServer are on a 128GB mSATA SSD and the music (16,806 tracks) is on a 1 TB SATA SSD.
This is certainly more performance than RoonServer requires, but I am planning on running HQPlayer on it when integrated with Roon to upsample Redbook, including Tidal, and possibly also use the convolution engine for Room EQ. That real time processing is the reason for the higher spec and hopefully might be done without turning on the fan (remains to be seen).
Brian’s news that HQP need not be on the same machine as the Roon Core is very interesting and opens up more flexibility of architecture.
