ARGB mini tower case with DarkMirror front panel

The Cooler Master MB320L ARGB MasterBox is a beautiful mini tower case with a stunning "DarkMirror" front panel and tempered glass side panel. In this case every detail has been carefully thought out to allow you to build the Micro ATX or Mini ITX configuration of your dreams, both compact and powerful.

The included ARGB fans can be complemented by other fans, but also by a watercooling system.

    Good little box

    Good value for money with this box. Installation of the configuration is straightforward and the design is attractive. The only drawbacks are that the cable management is not very intuitive and there are only 2 fans on the front panel.
