Cooler Master MasterBox NR600 Case Review

Not everybody wants or needs a case crafted from exotic materials or decked out with crazy integrated lighting shows. In fact, there are tons of PC enthusiasts out there that can’t stand RGB products and go out of their way to find components that don’t feature what they consider to be an unnecessary or foolish trend. Thankfully, Cooler Master understands that, and they have provided a new case in their mid-tower MasterBox line that may appeal to that crowd. The NR600 has a sleek and simple design that streamlines form and function. That being said, the NR600 isn’t void of useful features, and if you follow along, you will get to see that for your self.

We would like to thank Cooler Master for providing our review sample of the MasterBox NR600.

As is pretty standard, the NR600 comes packaged in a brown cardboard box with a basic illustration of the case on the front of the box. The name of the case is shown in large lettering towards the bottom, and a sticker placed in a box designated that our review sample came without an optical drive bay.

The back side of the box shows both versions of the case, and provides a bit of a narrative about the case. Also shown are a few of the case’s features and a bit of information about them.

Inside the box we found the NR600 flanked by two closed-cell foam pieces, and the case itself was wrapped in a plastic bag, about as standard as it gets.

Included with the NR600 is an instruction manual and warranty information, as well as a bag containing the various screws, standoffs, brackets, and other installation accessories that we have come to expect over the years.
