Purpose-built E-ATX chassis

The Corn Electronics GR701 is a full-tower case designed for E-ATX, ATX, Micro-ATX and Mini-ITX motherboards. It targets builders who want extensive liquid-cooling clearance and a distinctive Gundam-themed finish with UV printing that resists fading.

Capacity and headroom

Dual 420 mm radiator mounts at the front and top handle high-heat CPUs and GPUs, while a 460 mm GPU length limit and 190 mm CPU cooler height cover most flagship cards and air coolers. The 34 mm cable-routing channel and nine expansion slots plus three vertical positions give room for complex builds, but the 240 mm PSU length cap excludes some longer units.

Thermals, noise and power

Four pre-installed 140 mm PWM fans (three front, one rear) move air through removable front, top and bottom dust filters. An integrated ARGB fan hub and LED control button let you tune lighting and fan curves without extra controllers. Front I/O includes a 60 W fast-charge USB Type-C port alongside four USB 3.2 Gen1 ports, one USB 3.2 Gen2 Type-C and a combined audio jack.
