FS: 2012 Apple Mac Mini Been running Roon for the last 2 years but "upgraded" to a newer M1 Mini for software development. This has been solid. Spec: 2.5 GHz Intel "Core i5" 8GB Ram installed 500GB HDD 4 USB 3 ports Full specs: https://everymac.com/systems/apple/mac_mini/specs/mac-mini-core-i5-2.5-late-2012-specs.html Currently installed with MacOS 10.14 Mojave and I believe you can upgrade to 10.15. $200 shipped including PP for Friends and Contribs only right now. OR $225 shipped with additional 128GB SSD I can add and install if prefered the 128GB SSD I was using for another $25. The 500GB will also be included. Perfect to boot off the SSD and have the 500GB drive for music/media. NOTE: you'll need to supply a external enclosure. ~$14 on amazon.
