The Cooler Master, Masterbox NR200 is a small form factor case that is loaded with possibilities. It has room for triple-slot graphics cards, tons of cooling options with support for 155mm CPU tower coolers, or up to 280mm AIO coolers.
This case is sure to be popular with the small form factor crowd. I, for one, love this case. I know it’s not the smallest of PC cases but with its flexibility, tool-free access, and the fact that you don’t have to sacrifice cooling for size. Make the NR200 a great option at a price that is accessible for all to enjoy.
Key Features
The MasterBox NR200 takes all of the features found in a core performance ATX chassis and efficiently utilizes them in a space less than half the volume. Every feature is thoughtfully laid out in the 18-liter case to maximize component compatibility, ease of use, and thermal efficiency.
Open ventilation and multiple fan mounts bring airflow where it’s needed, while generous water cooling and air cooling clearances allow the fitment of coolers that can take advantage of all the airflow. Ample clearance for long, triple-slot graphics cards means no sacrifices are needed in GPU power to take advantage of small form factor sizing. The frame is wrapped in a sleek and tasteful steel chassis that blends in perfectly on top of desk.
- Vented Panel: The NR200 is flanked with five ventilated steel panels for unrestricted airflow.
- 360 Degree Accessibility: Every panel and frame part can be dismantled to allow advanced disassembly and 360 degrees of access to work on components.
- High-quality Materials: Thick, powder coated SGCC steel lasts the life time of the chassis and resists marring from transport or handling.
- Custom Cooling Support: Two liquid cooling pump locations alongside side and bottom radiator mounting locations allow for powerful, custom water-cooled builds inside a compact enclosure
- Easy, Tool-free access: All external panels, including the tempered glass and top-mounted fans, are secured with pins for easy removal, facilitating quick access to the internals without the use of tools.
- Unrestricted Cooling Potential: Holds up to 7 fans. 5 sides of open ventilation. Fits CPU coolers up to 155mm tall or up to 280mm long radiators.
- Full-size GPU Compatible: Triple slot GPUs are supported with a maximum length of 330mm and maximum width of 156mm. Vertical mounting is optional.

Cable management
Cable management in the NR200 isn’t a thing, but that’s usually the case with this form factor. Cooler Master does, however, provide a few Velcro straps around the power supply cage to tidy up some of the cables.
Cooling
The Masterbox NR200 is capable of housing as many as 7 case fans. Two of them at the top. Two at the bottom, two on the side, and one at the rear of the case. The CPU can be fitted with a tower cooler up to 155mm in height, or with an AIO up to 280mm in length. There are also mounting holes for a pump if you would like to go custom water cooling.
During the stress tests I performed, the temperatures were great considering the form factor. Even with the stock rear 92mm fan and one top 120mm fan, during full load, my CPU temps never rose above 64 degrees, and GPU temps were hovering around 68 degrees. Those very acceptable under load temperatures are thanks to the NR200’s panels, which provide excellent airflow.
Custom water cooling is also a great option with this case as it has plenty of room for a pump and radiator support for up to a 280mm rad. I have already been planning a custom loop for this case here shortly.
Cleaning
Cleaning the NR200 is pretty straight forward as four sides of the case have a magnetic mesh filter that can be removed easily for cleaning. The tool-free access makes getting at the filters for cleaning a snap. I hope more companies adopt this method as it is IMO a better way of attaching the panels.
Front I/O
The front panel I/O has a power, reset, 2 USB 3.0, and a combo headphone/mic jack. The power and reset buttons both have a nice tactile feel to them, which ads a nice modern touch.
