## Long description

The Cooler Master MasterBox 500 Midi Tower in black combines a compact gaming-oriented chassis with enhanced airflow and customizable ARGB lighting. The case features a geometric front panel with circuit-inspired ARGB accents, a removable top panel for easier installation of cooling components, and a tempered glass side panel for quick tool-free access. It supports multiple fan and radiator configurations, standard ATX-compatible components, and offers space for longer graphics cards and tall CPU coolers.
Advantages
The case delivers high cooling potential with support for up to seven 120 mm fans and dual 360 mm radiators, while FineMesh front-panel material balances maximum airflow and dust filtration. Pre-installed ARGB SickleFlow fans and an ARGB control button on the I/O panel enable immediate, customizable lighting. A removable top panel and a pin-secured tempered glass side panel allow tool-free access and simpler assembly.
