General Specifications

Cooler Master’s documentation identifies the case as an Iron Grey mid-tower measuring 544 × 248 × 546 mm and weighing 14.2 kg.

Motherboard Compatibility

The H500M supports a wide range of motherboard formats, including larger enthusiast boards:

• E-ATX — up to 12 × 10.7 inches
• ATX
• Micro-ATX
• Mini-ITX

This makes it suitable for everything from compact enthusiast systems to large ATX/E-ATX gaming workstations.

Expansion Slots

• 7 standard horizontal expansion slots
• 2 additional vertical GPU slots
• Total: 7 + 2
• Supports vertical graphics-card installation

The case also includes a graphics-card support arm, useful for supporting large and heavy GPUs.

Graphics Card Clearance

• Maximum GPU length: 412 mm

This provides enough room for many modern high-end graphics cards, although radiator/fan configuration can affect the usable clearance in particular installations.

CPU Cooler Clearance

• Maximum CPU cooler height: 190 mm

This allows the H500M to accommodate a wide selection of large tower-style air coolers.

Power Supply Compatibility

• PSU type: ATX PS2
• PSU location: Bottom-mounted
• Maximum PSU length: 200 mm

ARGB Lighting & Controller

The two 200 mm front fans are equipped with addressable RGB lighting.

The case includes an ARGB controller, allowing the lighting to be controlled directly from the case. The ARGB system can also be integrated with compatible motherboard RGB software/hardware through the appropriate ARGB connection.

Front Panel Design

A particularly useful feature of the H500M is the inclusion of two interchangeable front panels:

• Tempered-glass front panel — prioritizes the appearance and visibility of the front fans.
• Mesh front panel — prioritizes airflow.

The panels can be swapped depending on whether the build is being optimized more toward aesthetics or airflow.

Tempered Glass & Internal Design

The H500M uses four tempered-glass panels, giving the internal components extensive visibility. Cooler Master also incorporates multiple internal covers to produce a cleaner-looking finished build.

The chassis includes nine covers designed to hide cables and other internal components and maintain a cleaner presentation. The PSU cover can also be configured to expose the power supply when desired.
