MasterFrame 400 Mesh

The MasterFrame 400 Mesh is a premium open-frame compact chassis crafted for Micro-ATX and Mini-ITX platforms. Embracing the FreeForm 2.0 design philosophy, it features a precision aluminum frame, dual-orientation support, and enhanced mesh airflow. With premium aesthetics and performance-grade clearance, it empowers creators and builders to push compact PC design further.

FreeForm 2.0 Exo-structure

The exposed aluminum frame supports versatile positioning and adapts seamlessly to both vertical and horizontal layouts.

Dual-Orientation Ready

Stand it tall, lay it flat, or flip it sideways. Detachable feet and a smart, adaptable design make it easy to fit any workspace or creative setup.

*Vertical orientation may require additional accessories or adapters depending on component layout, connector clearance, or cable routing.

Compact Motherboard Compatibility

Supports Mini-ITX and Micro-ATX motherboards, delivering optimal compatibility for compact, high-performance builds without compromising cooling or component clearance.

Ample GPU Clearance

Accommodates graphics cards up to 390mm in length, providing full compatibility for high-end GPUs and future upgrades.

Extensive Cooling Support

Supports up to nine fans, including 200 mm fans compatibility, plus top-mounted 360 mm radiators for superior airflow in a compact build.

TOOL-FREE PANEL REMOVAL

Easily remove side panels without tools for quick access and modifications during build or upgrades.

INCLUDED GPU SUPPORT BRACKET

The included GPU support bracket prevents GPU sag and ensures stability during intense gaming or high-performance workloads, maintaining a clean and secure build.

MODERN FRONT I/O

Stay connected and ready for anything—MasterFrame 400 Mesh features USB 3.2 Gen 2×2 Type-C, dual USB 3.2 Gen 1 Type-A, and a combo audio jack for ultra-fast data, charging, and seamless peripheral support.
