It offers unparalleled modularity and cooling potential for those who prioritize airflow and visual hardware display, though it requires a workspace that can accommodate an exposed design that may accumulate dust more quickly than traditional closed cases.

What is the maximum GPU length supported?

Are the mounting feet included?

Troubleshooting

GPU sag after installation

Adjust the included GPU support bracket to sit flush against the underside of your graphics card.

ARGB fan not lighting up

Check that the ARGB cable is securely connected to a 5V header on your motherboard and that your software control is enabled.

Excessive component dust buildup

Ensure the chassis is placed on an elevated surface away from floor-level air currents and perform regular cleaning with compressed air.

Pros and Cons

Pros

  • Flexible vertical or horizontal orientation
  • Excellent airflow due to the open-frame design
  • Support for large 360mm radiators
  • Tool-free design simplifies the building process
  • Includes one high-performance 120mm SickleFlow ARGB fan

Cons

  • Open-frame design requires more frequent dusting
  • Provides no sound dampening for components
  • Not suitable for environments with small children or pets
  • Requires careful cable management as components are visible

Setup, Compatibility & Care

When setting up the MasterFrame 400, ensure you have a clean, stable surface, as the open frame does not protect internal components from spills or debris.

  • Motherboard Compatibility: Strictly designed for Micro-ATX and Mini-ITX motherboards.
  • Orientation: Decide on your layout (vertical or horizontal) before fully mounting your power supply and cables to ensure the best cable routing path.
  • Cleaning: Because of the open design, use compressed air at least once a month to remove dust from heatsinks and fan blades.
  • Cable Management: Use zip ties or velcro straps to bundle cables along the frame structure to maintain a clean aesthetic.
