A Closer Look - Inside

To gain access to the Masterbox NR600, simply remove the thumb screws holding each panel in place. The interior is all black and there are fairly compact, slightly angled grommets for you to route your cables through. Cooler Master has included plenty of zip tie hooks for easy and clean cable management. There are two 2.5" hard-drive mounting location along with a single 3.5" one on the motherboard tray itself.


On top of that, the shroud allows for three more 2.5" drives, which can then easily be seen when looking at the internals through the windowed side.


Last but not least, there are three additional 3.5" hard-drive bays underneath the shroud, bringing the total up to four 3.5" and five 2.5" drives, which is plenty for most users. Above that, in the front, it is all about cooling. You may install two additional 120 mm fans here or place a 360 mm radiator in the front without sacrificing any expandability.


The PSU bay underneath the shroud is pretty basic, with foam tips to minimize vibrations moving on to the chassis frame. Above that are the eight expansion slots, with each cover held in place by a traditional screw. In the very top, the height-adjustable 120 mm fan with its 3-pin fan header is set to push air out the back.


In the ceiling, you can clearly see the mounting holes for fans or a radiator. Watch out if using a thick 280 mm rad as it may clash with components on the installed motherboard. However, if you are going that route, odds are you will spend more on a chassis as well.


All the cables within the NR600 are of the default variety and completely black.
