Cooler Master MasterBox MB311L

This PC case Cooler Master MasterBox MB311L has a size of Midi Tower and offers a beautiful construction, especially its nice black colour. This colour was applied to the steel construction. The Midi Tower format is designed for powerful PCs for spaces that would not fit a Big Tower. Though this is a smaller PC case, it will fit a great amount of professional or gaming units. An advantage of this type of chassis is the possibility of good dissipation of heat, thanks to the medium or large coolers and fans. They will fit into the case easily. The main control panel of your desktop computer, allowing the connection and control of peripherals, is located on the top of the chassis. One can install a mATX (Micro ATX) and mITX (Mini ITX) type motherboard into the Cooler Master MasterBox MB311L case. The front of the case is perforated, allowing for better ventilation inside.
