Full-tower E-ATX chassis for high-end builds

The Corn Electronics GR701 supports E-ATX, ATX, Micro-ATX and Mini-ITX motherboards up to 12 by 10.9 inches. It fits graphics cards up to 460 mm long and CPU coolers up to 190 mm tall. Four 140 mm PWM fans are pre-installed at the front and rear for immediate airflow.

Dual 420 mm radiator mounts with metal GPU holder

Front and top panels each accept radiators up to 420 mm or three 140 mm fans. A rear 140 mm or 120 mm radiator is also supported. The metal GPU holder prevents sag on heavy cards, while removable dust filters on front, top and bottom simplify cleaning.

Replaces mid-tower cases limited to 360 mm cooling

Builders moving from a chassis that caps radiator support at 360 mm gain the 420 mm option for lower fan speeds or higher overclocks. The 34 mm cable-management space and 240 mm PSU clearance keep the interior tidy. Buyers needing more than two 3.5-inch drive bays or a lighter case for frequent moves should look elsewhere.

Questions about this item

What USB standard does the front USB-C port use and what speed does it cap at?

The front panel includes one USB 4.0 Type-C port that can run at up to 40 Gbps, though some regions receive a USB 3.2 Gen 2x2 Type-C port instead.

How much clearance does the case allow for a CPU air cooler and a graphics card?

Maximum CPU cooler height is 190 mm and maximum GPU length is 460 mm.

What steps are needed to mount the motherboard and where do builders often go wrong?

Install motherboard standoffs matching the E-ATX, ATX, Micro-ATX or Mini-ITX pattern, then secure the board with screws; a common mistake is forgetting the extra standoffs required for the wider E-ATX layout.
