Product details
The Masterbox from Cooler Master is a well-thought-out, sleek case with excellent performance. The fully mesh front panel with a fan ensures outstanding airflow by default.
A large transparent plastic side panel provides a complete view of the installed components. Inside, great attention is paid to design and mounting options. The power supply is neatly hidden under a panel that also offers space for cable management. The hard drives have their own compartment at the bottom of the case, keeping them largely out of sight.
The case accommodates graphics cards up to 410 mm in length and CPU coolers with a maximum height of up to 167 mm.
