COOLER MASTER N400

The N400 is a member of Cooler Master's all-new N Series computer cases. All members of the N Series feature a mesh front panel that provides modern styling and optimized ventilation. Water cooling is fully embraced as N400 supports up to 240mm radiators for extreme cooling performance. Multiple dust filters located throughout the chassis make system maintenance simple and convenient.

SUPERIOR VENTILATION

EXCELLENT WATER COOLING SUPPORT

The N Series features a premium, fully meshed front panel that allows substantial airflow to pass through the chassis. Strategic placement of the included fans provide optimum cooling for internal components out of the box.

Flexible mounting options including support for a 240mm radiator along the right side and 120mm at the rear.

SIMPLIFIED CLEANING AND MAINTENANCE

OPTIMIZED STORAGE SPACE

Multiple filters can be found throughout N400 (top, right, bottom) to make cleaning dusty build ups a breeze.

8 HDDs can be used to fill up all 3.5" drive bays, or replace two with SSDs in the tool-less slots. An additional SSD can be mounted at the bottom of the hard drive cage to reach maximum storage capacity.

Customers are mixed about the fit of the computer chassis. Some mention that everything fits very well, while others say that the screws specified for the motherboard standoffs don't fit, the CPU cooler restricts the motherboard size, and the space is very tight and would not be convenient.

Great mid-tower case
5 Stars
Great mid-tower case
Great mid-tower case. Cooler Master has added a lot of features for a respectable price. Only downside is that the side panel window is tinted and rather small. This case did fit the Corsair H105 cpu cooler on the right side panel 240mm intake.Now mine is modded and custom water-cooled. Had to drill out the bottom hard-drive cage rivets to fit the 54mm thick radiator and cut a small piece out of the top 5.25 bay to fit my reservoir. Overall very pleased with this purchase.
