Ready for 360 mm radiators and 390 mm GPUs

The MSI MAG FORGE 321R AIRFLOW is an ATX mid-tower built around a mesh front and side panel that supports up to 11 fans. It ships with four 120 mm ARGB fans already installed at the front and rear. A 4 mm tempered glass side panel shows the interior while magnetic dust filters cover the top and side vents.

Check motherboard size, cooler height and PSU length

The case accepts Micro-ATX, ITX and Mini-ITX boards only; full-size ATX boards will not fit. Verify that your CPU cooler is no taller than 160 mm and that the power supply is no longer than 200 mm. Ensure the graphics card does not exceed 390 mm in length. Confirm your front-panel header layout matches one USB 3.2 Gen 2x2 Type-C and two USB 3.2 Gen 1 Type-A ports.

Pre-installed ARGB fans

Four addressable RGB fans provide immediate airflow and lighting without extra purchases. The included ARGB control board lets you synchronise effects through a motherboard header or the case button. Magnetic dust filters on the top and side vents can be lifted off for cleaning in seconds, reducing dust build-up on components. Two 3.5-inch bays and one dedicated 2.5-inch bay handle storage, with the 3.5-inch trays also accepting 2.5-inch drives up to three total.

Questions about this item

Does the MSI MAG FORGE 321R AIRFLOW come with fans pre-installed, or do I need to buy them separately?

Four 120 mm ARGB fans are already fitted — three at the front and one at the rear — so no extra fans are required for basic airflow.

Which motherboard form factors fit inside the MAG FORGE 321R AIRFLOW?

The case accepts ATX, Micro-ATX and Mini-ITX boards, giving you the full range of standard desktop sizes.

Will a 390 mm graphics card and a 360 mm radiator fit together in this chassis?

Yes, the 390 mm GPU clearance and top-mount support for a 360 mm radiator allow both to be installed at the same time.
