Custom UV-printed full-tower case

The Corn Electronics GR701 is a high-quality E-ATX chassis finished with UV printing that resists colour fading. It targets enthusiasts who want a personalised theme and extensive liquid-cooling support in a single heavyweight enclosure. Custom graphics can be ordered directly from the manufacturer for a unique build appearance.

Pre-installed fans and vertical GPU brackets

Four 140 mm PWM fans come fitted at the front and rear, so airflow works straight from the box. Removable dust filters on the front, top and bottom simplify cleaning. The 34 mm cable-management channel eases routing, though the case weight of 20.8 kg makes handling and transport more difficult than average.

420 mm radiator clearance and 460 mm GPU limit

Dual 420 mm radiator mounts at the front and top give ample headroom for high-wattage custom loops. The 190 mm CPU-cooler height and 460 mm GPU length accommodate most flagship air and liquid coolers. Builders needing more than nine expansion slots or a PSU longer than 240 mm will find the layout restrictive.

Questions about this item

How do I verify the four pre-installed 140 mm PWM fans are spinning correctly after building in the GR701?

Power on the system and check each fan visually through the tempered glass panels; all four 140 mm PWM fans should spin smoothly and respond to speed changes in the BIOS or fan-control software.

Which items come in the box with the GR701 and which parts must be purchased separately?

The case includes four pre-installed 140 mm PWM fans, a metal GPU holder, an ARGB fan hub, removable dust filters for front, top and bottom, and front I/O with USB 3.2 Gen1, USB 3.2 Gen2 Type-C and a USB 4.0 or 3.2 Gen 2x2 Type-C port; motherboard, CPU cooler, graphics card, power supply and storage drives are not included.

Which GR701 version should I choose if I need the standard Mario Red model with 420 mm radiator support?

Select the standard GR701 E-ATX version in Mario Red; it supports 420 mm radiators at the front and top, fits E-ATX boards up to 12 x 10.9 inches, and weighs 20.8 kg.
