E-ATX full tower with 420 mm radiator support

The Corn Electronics GR701 is a full-tower chassis built for E-ATX, ATX, Micro-ATX and Mini-ITX motherboards up to 12 by 10.9 inches. It ships with four 140 mm PWM fans pre-installed at the front and rear, and includes a metal GPU holder for cards up to 460 mm long. The layout suits builders planning high-capacity liquid cooling or heavy graphics cards.

Front and top 420 mm radiator mounts

Both front and top positions accept radiators up to 420 mm alongside three 140 mm fans each, while the rear takes a 120 mm or 140 mm unit. Removable dust filters cover front, top and bottom intakes, and tempered glass on both side panels exposes the interior. A maximum CPU cooler height of 190 mm and 34 mm cable-management space keep airflow paths clear.

ARGB fan hub and 60 W USB Type-C front I/O

An integrated ARGB hub controls lighting for the pre-installed fans, and the front panel provides a headphone jack, four USB 3.2 Gen 1 ports, one USB 3.2 Gen 2 Type-C and either USB 4.0 or USB 3.2 Gen 2x2 Type-C at 60 W charging. Vertical GPU mounting adds three extra expansion slots, while drive bays hold five 2.5-inch drives plus two combo 2.5/3.5-inch bays.

Questions about this item

How do I mount the four pre-installed 140 mm PWM fans and the 420 mm radiator without blocking the front panel?

The front and top each accept three 140 mm fans or a 420 mm radiator; use the included brackets to secure the radiator first, then clip the fans onto the same rails so the front I/O stays clear.

Which dust filters need regular cleaning and how are they removed?

Removable mesh filters sit at the front, top and bottom; pull each frame outward, rinse with water, dry fully and slide back into the grooves.

What is the maximum CPU cooler height before it hits the side glass?

The case allows up to 190 mm from motherboard tray to the tempered glass panel; measure your cooler including fan clips to stay under that limit.
