Introduction
The Cooler Master MasterBox CM694 E-ATX Mid-Tower Cabinet is built for users who need a flexible chassis with substantial storage capacity and broad hardware compatibility. Its curved mesh front, black finish and practical internal layout make it suitable for a wide range of enthusiast PC configurations.
The cabinet supports Mini-ITX, Micro-ATX and ATX motherboards, along with compatible E-ATX boards up to 12 × 10.7 inches. Modular drive cages let builders adapt the internal layout to their storage and cooling needs, while top radiator support up to 360mm provides additional options for liquid-cooled systems.
Features and Technologies
Curved Mesh Front Panel
The curved mesh front gives the CM694 its distinctive appearance while allowing air to enter through the front intake. It complements the included front fans and provides a practical foundation for cooling-focused builds.
Flexible Drive Cage System
Three modular drive cages accommodate a large collection of storage drives. Removing selected cages can create extra room for front radiators or longer component configurations, depending on the intended layout.
Graphics Card Stabiliser
The stabiliser helps support compatible graphics cards inside the chassis. The available GPU length depends on the stabiliser position and whether drive cages remain installed.
Three Pre-installed 120mm Fans
Two front intake fans and one rear exhaust fan are included. Additional supported fan positions at the front and top allow the cooling configuration to be expanded.
Extensive Radiator Support
The top supports compatible radiators up to 360mm. Front radiator installation can require the removal of drive cages, with larger radiators also requiring removal of the optical drive cage.
Modern Front Connectivity
The front I/O panel includes two USB Type-A ports, one USB Type-C port and a combined headset jack for convenient access to supported peripherals and audio devices.
Built for Storage and Cooling Flexibility
The MasterBox CM694 stands out with its modular drive cage system, support for up to six 3.5-inch HDDs and eight 2.5-inch SSDs in the specified configuration, and radiator mounting options up to 360mm. Its layout allows builders to balance storage capacity, cooling and graphics card clearance. Some configurations require drive cage removal, so plan the full component layout before assembly.
Technical Specifications
Specifications refer to the steel-side-panel model MCB-CM694-KN5N-S00. The tempered-glass variant has a different model number and slightly different dimensions. E-ATX motherboard installation may limit cable-management options, and some front radiator sizes require removal of drive cages and the optical drive cage. Confirm the exact SKU and configuration before purchase.
Ideal Use Cases
High-End Gaming PCs
Build a gaming desktop with a powerful graphics card, compatible cooling hardware and multiple storage drives.
Creative Workstations
Suitable for workstation configurations that need flexible component placement and substantial local storage.
Storage-Heavy Builds
The modular drive cages support multiple HDDs and SSDs for large media libraries, backups and data-intensive projects.
Custom Liquid-Cooled PCs
Compatible radiator mounting positions and a flexible interior help builders plan a suitable liquid-cooling arrangement.
Before You Buy / Install
- Confirm the exact model number. The steel-side-panel model MCB-CM694-KN5N-S00 differs from the tempered-glass variant MCB-CM694-KG5N-S00.
- E-ATX motherboard support is limited to boards up to 12 × 10.7 inches, and installation can reduce cable-management space.
- Check the graphics card length against the stabiliser and drive cage arrangement. The maximum available clearance changes with the internal layout.
- Front radiator installation can require removing two of the three drive cages. A 280mm or 360mm front radiator also requires removing the optical drive cage as specified.
- For top radiator installations, follow the recommended mounting arrangement: radiator below the bracket and fans above it for maximum compatibility.
- Check PSU length and drive cage placement before assembly; the available PSU clearance is reduced when a drive cage occupies the rear position.
- Verify the number of included fans, storage brackets and accessories supplied with the exact unit before purchasing.
