Cooler Master MasterBox NR400

This PC case Cooler Master MasterBox NR400 has the size of Midi Tower and provides a stylish and beautiful design, especially the black colour. This colour is clear on the steel construction. The Midi Tower format is perfect for powerful home PCs for spaces where a Big Tower does not fit. Though this is a smaller PC case, it will fit a great amount of professional and gaming components. An advantage of this kind of case is the possibility of great dissipation of heat with the help of larger coolers and fans. They will fit into the chassis easily. The control panel of your desktop computer, allowing for the control and connection of peripherals, is located on the top of the chassis. One can incorporate a mATX (Micro ATX) and mITX (Mini ITX) type motherboard into the Cooler Master MasterBox NR400 case. The front of the PC case is perforated, which allows for better ventilation inside.
