“Clever screwless assembly. Includes a small heatsink in the box and also a fan is already integrated into the case, so no need to buy a separate one which is nice and saves a little money.
The fan has a high pitched whine when it powers up. This doesn't usually bother me as it only powers up when necessary, which is typically when I'm watching a video and the sound of the video is sufficient to drown it out. The fan then powers down shortly after the video stops. However you might want to bear the fan noise in mind if you are doing something continuously processor intensive with it in a quiet room. If the Pi is largely idling the fan won't power up anyway and there will be no noise.
One minor thing I might have liked different is the reset button is flush with the case so you need a fingernail or tool to press it. I guess some people may want it this way to avoid pressing the button by accident but I would have preferred it to be more easily accessible.”
