Showcase frame for themed builds

The MasterFrame 360 Stage Mirror is an open-frame chassis built around a front mirrored platform that reflects components and collectibles from every angle. It accepts Mini-ITX, Micro-ATX, ATX and ATX BTF motherboards and clears graphics cards up to 430 mm long. The layout is intended for creators and collectors who want unrestricted placement of hardware and accessories.

Thermal headroom with flexible fan choices

Six 120 mm fan mounts on the top and six on the bottom support sizes from 120 mm to 200 mm, and both locations accept radiators up to 360 mm. Mesh dust filters cover the intakes while the open structure lets air move freely through the frame. A 145 mm CPU cooler limit and 210 mm PSU length keep the internal volume compatible with common high-performance parts.

Single USB 4.0 Type-C front port

The front I/O panel provides one USB 4.0 Gen 2x2 Type-C connection running at 20 Gbps, two USB 3.2 Gen 1 Type-A ports and a combined 3.5 mm headset jack. This port mix decides whether the case matches a motherboard with a matching internal header and whether the builder needs that bandwidth for external storage or docks.

Questions about this item

How do I mount the motherboard on the open-frame layout and which step is often missed?

Secure the board to the supplied tray using the standard ATX standoff pattern, then fasten the tray to the frame; the step most builders skip is installing the I/O shield before lowering the board into place.

What maintenance will the mesh dust filters need over time?

The mesh-only filters on the intake areas should be removed and cleaned with compressed air or a soft brush every few months to prevent airflow restriction.

What is the first thermal limit reached when running a 360 mm radiator with twelve 120 mm fans under sustained load?

The 145 mm CPU-cooler height clearance becomes the limiting factor, restricting the choice of water-block or air cooler that can fit above the motherboard.
