Product information

Description

The Cooler Master MasterBox 520 Mesh Midi Tower in black is a mid-tower PC case that combines airflow-focused design and customizable ARGB lighting. It ships with three pre-installed 120 mm ARGB front fans and supports multiple fan and radiator configurations. The case accepts ATX, EATX, Micro-ATX, Mini-ITX and SSI CEB motherboards, accommodates 2.5" and 3.5" drives, and offers a tempered glass side panel and removable top panel with dust filtering for easy maintenance and installation.

Advantages

Pre-installed ARGB lighting and three 120 mm front fans provide immediate cooling and visual customization. The mesh front and ventilation-focused layout prioritize airflow to improve thermal performance. A tempered glass side window displays internal components while a removable top panel and accessible dust filter simplify cleaning and upgrades. The case supports a wide range of motherboard sizes and multiple storage options, making it flexible for different build needs.

  • Gaming PC builds that require good airflow and ARGB lighting
  • Mid-tower systems using ATX, EATX, Micro-ATX, Mini-ITX or SSI CEB motherboards
  • Users who want visible components behind tempered glass
  • Systems needing multiple 2.5" and 3.5" drives

How to use

Install the motherboard matching one of the supported form factors on the included standoffs, mount the power supply in the designated compartment, and attach storage drives to the appropriate 2.5" or 3.5" brackets.
