I run Roon core on Dell PowerEdge T30 Xeon E3-1225V5 running Ubuntu 18.04 with absolutely no issues. In addition, I operate this alongside CCTV and Plex. The system drive is SSD (ext4) with ZFS pool for storage.
I picked up the server new for £330 complete with 8GB ECC, 1TB HDD, CD-RW and the processor. I added an extra 8GB ECC and would like to replace the processor with the Skylake Xeon E3-1260L v5 at some point.
The only downside to the server is that it only supports four SATA devices; an add-on card is needed to extend this. It’s very quiet and handles its workload very well.
Ha Ha this is a great description of the computer. I am running my Roon Core on a dual Xeon machine (Dell Precision 690) as well that is heavier than a tank, the fans are noisy, but it just keeps going and going and going. Craigslist purchase but it had 64GB of memory, four hard drives, plenty of overhead to run the Core without even going over about 15% processor power. It just sits on a shelf in the basement and runs everything (including a DivX movie server, JRiver server and others) and I don’t even know it’s there. Win 7 setup. I have also thought about something newer and quieter and smaller but don’t know what I would gain by it, what I have just works so I leave it alone.
I use a Dell PowerEdge T630 with 2x Intel Xeon E5-2630L v3 @ 1.80 GHz 8 core (16 threads) CPUs and 48 GB for running RoonServer, however not Linux but Windows Server 2012 R2 Essentials. RoonServer, Plex Media Server and some other applications run directly under Windows Server 2012 R2 Essentials, other applications (eg. Logitech Media Server, Universal Media Server, Image Bank Server, DBPowerAmp) run virtualized unter VMWare Workstation Prof.
I have not tried upsampling to DSD512 so far, but would expect that a Xeon server is capable of doing this like an i7, if the clock speed suffices. The clock speed can obviously be the limiting factor for one thread processing tasks.
