I have used 3 successive Mac Minis for dedicated music servers. They have been pretty trouble free and easy to operate.
Currently:
Mac Mini M1>iFi Zen Signature V2>Linn Akurate Kontrol>Linn AV5125 Aktiv>Linn Keilidhs
I use Roon, Qobuz, Apple Music and Spotify.
I control Roon through an iPhone, iPad or MacBook Pro. The interface is clean and easy to use.
You will need a keyboard, mouse and monitor to set the Mini up, but then will be able to go headless after you have installed your source preferences.
The ambient noise level in my living/listening room hovers around 28 dB, so any “dirty” computer noise is certainly below my threshold. Roon accesses all of my legacy iTunes library, which is a mix of CD burns, HD tracks downloads, mp3s and more than a few experimental LP>digital transcriptions before I got tired of that process.
The Mini is connected by Ethernet to my router, and all three that I have used have been really reliable.
You must understand that all of the opinions in play here exhibit a bias of one sort or another, Apple-haters, NUC-ers, golden ears, etc.
The streaming part of my set-up cost approximately $600. It takes a little time to disable some of the background programs in the Mini, but it works.
