I own one and I'm pretty happy with it. The main mistake people make when buying a mini PC is not looking at noise benchmarks. Most people want to place it on top of their desk within arm's length. They get wowed by the paper specs and then are disappointed by the noisy fan that constantly ramps up and down.

About 90% of them don't even have PWM controls in the BIOS. The SER8 is fairly quiet by default but you can make it dead silent with a custom fan profile.
