Cooler Master MasterBox NR400

This PC case Cooler Master MasterBox NR400 is Midi Tower and offers a stylish construction, especially its nice black colour. This colour is clear on the steel construction. The Midi Tower PC case is designed for the construction of powerful PCs for spaces where a Big Tower will not fit. Though this is a smaller PC chassis, it will fit a great amount of professional and gaming parts. One advantage of this type of chassis is the possibility of good removal of excess heat with the help of larger coolers and fans. They will fit into the chassis easily. The control panel of your computer, allowing for the control and connection of peripherals, is located on the top of the chassis. You'll be able to insert a mATX (Micro ATX) and mITX (Mini ITX) type motherboard into the Cooler Master MasterBox NR400 case. The front of this case is perforated, which will allow for better ventilation inside.
