I’ve just pressed “buy” on a HP EliteDesk 800 G2 with i5 and 16GB RAM to run headless. I’m planning to start running Roon Core on Windows, as my Linux skills are a tad rusty.
I have a relatively small collection of 20,000 tracks streaming to a bunch of Chromecast Audios and a few Google Nest speakers. I’ve got mesh WiFi and am planning to hang the Core unit off the basement mesh using wired ethernet.
Maybe someday I’ll upgrade my speakers but for now, this is mostly about the usability of the Roon interface, particularly for my wife.
