E-ATX Full Tower with Dual 420 mm Radiator Support

The Corn Electronics GR701 is an E-ATX full-tower chassis designed for custom-loop or high-end AIO builds. It accepts motherboards up to 12 by 10.9 inches and provides nine expansion slots plus three vertical positions. Four 140 mm PWM fans come pre-installed for immediate airflow.

Front and Top Mounts Limited to 420 mm Radiators

Radiator support reaches 420 mm at the front and top, while the rear is restricted to 120 mm or 140 mm units. A 460 mm graphics card fits with room to spare, yet the CPU cooler height stops at 190 mm. Cable routing space behind the motherboard tray measures 34 mm.

Heavy Chassis Requires Careful Handling and Planning

At 20.8 kg the case demands two-person lifting and a sturdy surface. The metal GPU holder and dual tempered glass panels add rigidity but increase weight. Custom UV printing makes returns impossible, so verify all clearances before assembly begins.
