Minimalist ATX Mid Tower

The Cooler Master Elite 502 is a black steel and tempered glass ATX mid tower built for a clean, minimalist setup. It supports ATX, E-ATX, Micro ATX and ITX motherboards and includes dust filters on the bottom, front and top panels. Two 3.5-inch and two 2.5-inch internal drive bays provide storage flexibility.

410mm GPU clearance

The case fits graphics cards up to 410mm long, covering models such as the RTX 5090 and RX 9070 XT. A large intake grill feeds unrestricted airflow to the three pre-installed 120mm aRGB PWM fans at the front and one at the rear. Top mounts accept three more 120mm fans or a 360mm radiator.

Builders needing maximum radiator length

The top panel supports a 360mm all-in-one cooler, while CPU air coolers up to 170mm and power supplies up to 170mm also fit. Seven expansion slots give room for full-length cards. Buyers who want more than two 3.5-inch bays or a longer PSU allowance should look at something else.

Questions about this item

Does the 410 mm GPU clearance in the highlights match the 360 mm limit in the specs?

The specification sheet lists a maximum GPU length of 360 mm, so plan for cards up to that size.

What front-panel USB standard does the Type-C port use?

The I/O panel includes a USB Type-C connector; the exact USB generation is not detailed in the supplied data.

How much room is there behind the motherboard tray for a 3.5″ drive cage?

Two internal 3.5″ bays are provided, and the ventilated PSU shroud leaves space for cable routing around them.
