Full-tower case for custom builders

The Corn Electronics GR701 is an E-ATX full-tower chassis designed for enthusiasts who want extensive radiator support and a distinctive Kuromi-White finish. It accommodates motherboards up to 12 by 10.9 inches and graphics cards up to 460 mm long. The case includes a metal GPU holder and dedicated component storage for a tidy internal layout.

Dual 420 mm radiator mounts and pre-installed fans

Front and top panels each accept radiators up to 420 mm, while the rear supports 120 mm or 140 mm units. Three 140 mm PWM fans come fitted at the front and one at the rear, providing high airflow with speed control. Removable dust filters on front, top and bottom help maintain clean intake paths under load.

ARGB hub and 60 W USB charging

A built-in ARGB fan hub simplifies lighting synchronisation across the pre-installed fans. The front I/O panel adds a USB 4.0 or USB 3.2 Gen 2x2 Type-C port capable of 60 W fast charging alongside four USB 3.2 Gen 1 ports and audio jacks. Builders who need more than five 2.5-inch drive bays or a slimmer profile should consider other models.

Questions about this item

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

Install the three front 140 mm fans first, then attach the 420 mm radiator to the front brackets; the 5 × 2.5″ and 2 × 2.5″/3.5″ combo bays sit behind the motherboard tray so they stay accessible.

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

Magnetic filters on the front, top and bottom panels pull off without tools; clean them every few months to keep airflow to the three front 140 mm fans and top radiator unrestricted.

What thermal limit appears first when running a 420 mm radiator with the three front 140 mm fans at full load?

The 190 mm maximum CPU cooler height caps the radiator-and-fan stack at the top, so a thick 420 mm radiator plus fans can hit that ceiling before the GPU length or PSU limits are reached.
