Compact Micro-ATX Chassis

The Cooler Master Elite 301 is a white Mini Tower designed for Micro-ATX and Mini-ITX builds. It ships with three 120mm ARGB fans pre-installed at the front. A tempered glass side panel shows the interior. The front I/O includes USB 3.1 Gen 1, USB 3.1 Type-C and audio jacks.

Tool-Less Access and Clearances

The front panel lifts off using magnets so filters can be cleaned quickly. A magnetic dust filter also sits on the top panel. Maximum graphics card length is 365 mm without front fans or a radiator. CPU cooler height is limited to 163.5 mm. Power supply length must not exceed 160 mm.

Builders Who Want a Small White Case with ARGB

This case suits anyone building a compact system that needs strong airflow and a clean white aesthetic. It is not for buyers who need more than one 3.5-inch drive bay or more than two 2.5-inch drives. It is also not for builders planning an ATX motherboard or a radiator thicker than 280 mm.

Questions about this item

How can I confirm the three pre-installed 120mm ARGB fans are spinning at the rated 1200 rpm after I build in the Elite 301?

Connect the fan headers to a PWM-capable motherboard or the included controller, then use the board's BIOS or monitoring software to verify each fan reports 1200 rpm under load.

The Elite 301 ships without a power supply — what other components must I purchase separately to complete a build?

You will need a Micro-ATX or Mini-ITX motherboard, CPU, cooler no taller than 163.5 mm, GPU up to 365 mm, memory, storage for the single 3.5-inch bay and up to two 2.5-inch drives, and an ATX power supply no longer than 160 mm.

Which radiator size should I choose for the top mount if I want the largest liquid cooler the Elite 301 can accept?

The top panel supports radiators up to 280 mm, so a 280 mm AIO is the maximum size you can install in that position.
