I run my Roon Server on a QNAP NAS. The NAS has an 8th-gen i7 and 64GB RAM and Roon’s database lives on one of the NAS’ SSDs. If you already happen to have a QNAP or Synology NAS you could try running Roon Server on it before you spend big bucks on something you don’t need. And it’s dead-simple to set up. Seriously.
Oh yeah - the NAS is on all the time, so so is the Roon Server.
