Cooler Master MasterBox CM694 Mid Tower Case

The Cooler Master MasterBox CM694 is a mid-tower ATX chassis engineered for high-performance PC builds, featuring optimized airflow design with dual 120mm front intake fans and rear exhaust configuration to maintain thermal stability under sustained computational loads. System integrators and gaming PC builders rely on this case to house multi-GPU setups, high-end processors, and extensive storage configurations while maintaining superior cable management and component accessibility. The CM694 solves critical thermal management challenges in compact form factors by delivering efficient air circulation paths that reduce CPU and GPU temperatures by up to 8-12 degrees Celsius compared to standard mid-tower designs.

Product Overview

The Cooler Master MasterBox CM694 employs a dual-chamber design philosophy that separates the power supply compartment from the main component bay, creating independent airflow streams that prevent hot exhaust air from recirculating across critical components. The chassis features a steel construction with a mesh front panel that maximizes intake surface area while maintaining dust filtration through removable magnetic filters. The internal layout accommodates up to seven 120mm or 140mm fan positions, supporting advanced liquid cooling solutions with radiator mounting points on the front, top, and rear of the case.

What distinguishes the CM694 from competitors is its intelligent cable routing infrastructure with multiple pass-through grommets and a dedicated cable management bar that organizes power distribution without obstructing airflow paths. The case supports motherboards up to E-ATX dimensions, GPU cards up to 370mm in length, and CPU coolers reaching 160mm in height, providing exceptional compatibility for high-end components. The tempered glass side panel with anti-fingerprint coating offers visibility of internal components while the removable HDD cage allows flexible storage configuration for SSD-dominant builds.

How to Use

Begin assembly by removing the tempered glass side panel and both side covers to expose the internal cable management compartment and motherboard tray. Install the power supply first in the bottom chamber, routing the 24-pin ATX and 8-pin CPU connectors through the dedicated grommets into the main component bay. Mount the motherboard standoffs according to your motherboard size (ATX, Micro-ATX, or Mini-ITX), then carefully position the motherboard onto the tray, ensuring the I/O shield aligns with the rear panel cutout. Install the CPU cooler before mounting the motherboard if using tower-style coolers exceeding 100mm height to avoid interference with RAM modules.

Install your GPU into the topmost PCIe x16 slot, ensuring the card length does not exceed 370mm and that the rear bracket aligns with the expansion slot covers. Route all power cables through the rear cable management compartment, utilizing the multiple grommets and management bar to organize 24-pin, 8-pin, SATA, and PCIe power connectors without crossing airflow paths. Install storage drives in the removable HDD cage or directly in the 2.5-inch SSD mounts on the motherboard tray, then secure the cage back into position. Finally, install the pre-mounted 120mm rear exhaust fan and two 120mm front intake fans, verify all connectors are seated on the motherboard headers, close both side panels, and power on the system to confirm all fans spin and BIOS detects all components correctly.

Frequently Asked Questions

What is the maximum GPU length supported by the CM694 and will my graphics card fit?

The Cooler Master MasterBox CM694 supports graphics cards up to 370mm in length. Measure your GPU from the mounting bracket to the end of the card. Most modern GPUs including RTX 4070, 4080, and RX 7700 XT models fit comfortably within this specification. If your GPU exceeds 370mm, you may need to remove the HDD cage to gain additional clearance, though this reduces storage capacity.

Can I install a 360mm radiator in the front of the CM694 for liquid cooling?

Yes, the CM694 supports 360mm radiators in the front mounting position. The case provides adequate clearance for 360mm radiators with standard 25mm thickness. However, ensure your GPU length does not exceed 370mm when a front radiator is installed, as the radiator fans will occupy the front intake area. For maximum compatibility, measure your specific radiator and GPU combination before purchase.

How many storage drives can the CM694 accommodate and is the HDD cage removable?

The CM694 includes a removable 3.5-inch HDD cage with capacity for 4 drives, plus 4 additional 2.5-inch SSD mounting points directly on the motherboard tray. The HDD cage is tool-free removable, allowing users to eliminate the cage entirely for builds prioritizing SSD storage and improved airflow. This configuration flexibility supports modern NVMe-centric builds while maintaining backward compatibility with legacy SATA storage systems.

What is the thermal performance improvement of the dual-chamber design compared to standard mid-tower cases?

The dual-chamber design separates the power supply compartment from the main component bay, creating independent airflow streams. This architecture reduces hot air recirculation and typically improves CPU and GPU temperatures by 8-12 degrees Celsius compared to single-chamber mid-tower designs under sustained load. The mesh front panel and magnetic filters further optimize intake efficiency, making the CM694 an excellent choice for high-performance builds requiring sustained thermal stability.

Does the CM694 support E-ATX motherboards and what are the maximum dimensions?

Yes, the CM694 supports E-ATX motherboards with maximum width of 272mm. This allows installation of extended ATX boards with additional PCIe slots and power delivery systems. Verify your specific motherboard dimensions before purchase, as some E-ATX boards with extreme width may require careful cable routing around the motherboard edges. Standard ATX and Micro-ATX boards install without any spatial constraints.
