Full-tower E-ATX case with 420 mm radiator support

The Corn Electronics GR701 is a full-tower chassis designed for E-ATX, ATX, Micro-ATX and Mini-ITX motherboards. It ships with four pre-installed 140 mm PWM fans and includes a metal GPU holder plus a dedicated component storage area. An integrated ARGB fan hub and 60 W fast-charging USB Type-C port sit on the front panel.

Suits custom-loop builders.

This case targets enthusiasts planning dual 420 mm radiators or large air coolers up to 190 mm tall. Builders who need a small footprint, lighter weight or a standard mid-tower layout should look at smaller form-factor alternatives. The 20.8 kg mass and 268 mm width also demand a sturdy desk or floor space.

420 mm front and top radiator clearance

The defining specification is support for 420 mm radiators at both the front and top, paired with a 460 mm maximum graphics-card length. This combination decides whether a high-wattage custom loop or oversized GPU will fit without modification.

Questions about this item

How do I mount a 420 mm radiator in the front and what step is often missed?

Use the front 3 x 140 mm fan mounts for a 420 mm radiator; the step often missed is removing the three pre-installed 140 mm PWM fans first.

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

Removable dust filters on the front, top and bottom panels slide out for cleaning without tools.

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

The case allows a CPU cooler up to 190 mm tall before it contacts the tempered glass side panel.
