Mid-tower case for high-airflow builds

The MSI MPG GUNGNIR 300R AIRFLOW is a mid-tower chassis designed for builders who prioritise cooling performance. Its one-piece 1mm perforated front panel draws air straight into the interior. Four 120mm ARGB fans come pre-installed and sync with Mystic Light. Ten fan mounts in total allow extensive airflow configurations.

Dual 360mm AIO support and GPU clearance

The defining specification is support for dual 360mm liquid coolers at the front and top, including push-pull mounting. An omnidirectional graphics card bracket adjusts to hold heavy cards vertically or horizontally. The interior fits GPUs up to 360mm long and E-ATX boards measuring 280 x 305mm.

Front I/O and expansion headroom

The front panel provides one USB 3.2 Gen 2x2 Type-C port at 20Gbps and two USB 3.2 Gen 1 Type-A ports at 5Gbps. This covers modern peripherals and fast external storage. Builders needing more than ten fan mounts, additional front-panel connectivity or support for radiators larger than 360mm will need a larger enclosure.

Questions about this item

How does the one-piece 1mm perforated front panel affect airflow when a 360mm AIO is mounted at the front?

The perforated panel lets air pass freely so a front-mounted 360mm AIO can draw cool air directly through the mesh, and the case also supports a push-pull fan configuration on that radiator.

What does the USB 3.2 Gen 2x2 Type-C port’s 20Gbps rating mean for real-world transfer speeds?

The port is rated for 20Gbps theoretical bandwidth; actual speeds depend on the connected device and cable, but it is the fastest front-panel USB standard on this case.

What motherboard sizes and GPU length can physically fit inside the chassis?

The case accepts E-ATX boards up to 280×305mm, ATX, Micro-ATX and Mini-ITX, and clears graphics cards up to 360mm long.
