I use this as a ROCK (Roon Optimized Core Kit), and for this, it works flawlessly thus far. It can get a tad noisy when the fan ramps up, so I keep it in the office, away from the audio system.There was one screw missing for installing the m2 ssd, but I had one that would work in my box o' parts. Also, the other screw for the ssd  was made of cheap, horribly soft metal, and was torqued WAY too tightly from the factory. I nearly ruined it getting it out, and had to replace it with a better screw. I'd expect better materials at this price point.Nonetheless, the machine itself has been perfect once the build headaches were solved.
