Cooler Master 's NR400 MasterBox is a mini-tower case with a sleek and elegant design that features a tempered glass side window. Compatible with mini-ITX and micro-ATX motherboards, its optimised interior space accommodates the largest gaming components without sacrificing cooling efficiency.
The MasterBox NR400 relies on good cooling quality and is equipped with 2 x 120mm fans (1 front and 1 rear). A number of 120/140 mm slots are available to increase the cooling efficiency.
Compatible with a watercooling system, the NR400 can house a radiator from 120 to 280 mm in size and thus provide superior cooling to your entire system.
The MasterBox NR400 hides its game well. It can accommodate micro-ATX or mini-ITX motherboards to build a powerful gaming system. The case can accommodate a 325 mm graphics card and the processor is cooled by a cooling unit with a maximum height of 166 mm. There are also 4 PCI slots for expansion cards for your future PC. On the storage side, you can install 3 x 3.5" and 4 x 2.5" disks.
Two dust filters are also available to keep the heart of your machine clean, and the HDD cage is removable. What's more, it can be moved to make room for a larger power supply or a larger heatsink in the case of watercooling for example.

This micro-ATX case from Cooler Master is a very good design.
Very sober with a black design, not grey like the picture.
The tempered glass will sublirema your components :)
Finally a micro ATX case with 3 HDD 3.5 inch slots, plus 4 SSDs, the best!
