High-capacity E-ATX full-tower case

The Corn Electronics GR701 One Piece-01 White is an ATX full-tower chassis designed for builders who need E-ATX motherboard support up to 12 by 10.9 inches and extensive liquid-cooling headroom. It ships with four 140 mm PWM fans pre-installed at the front and rear, an ARGB fan hub and a metal GPU holder for heavy graphics cards.

Upgrade from mid-tower or limited radiator space

This case replaces enclosures that restrict radiator length to 360 mm or offer fewer than nine expansion slots, adding front and top support for 420 mm radiators and three additional vertical GPU slots. The jump is worth it when a custom loop or dual-radiator build demands 420 mm clearance and 34 mm of cable-management depth behind the motherboard tray.

Nine expansion slots and 460 mm GPU clearance

Five dedicated 2.5-inch bays plus two combo 2.5/3.5-inch bays handle large storage arrays, while the 460 mm maximum GPU length and 190 mm CPU cooler height accommodate current flagship components. Front I/O includes USB 3.2 Gen 1, USB 3.2 Gen 2 Type-C and a region-dependent USB 4.0 or USB 3.2 Gen 2x2 Type-C port with 60 W fast charging. Builders needing more than two 3.5-inch drives or a PSU longer than 240 mm will need a different platform.

Questions about this item

Will the 268 mm width and 659 mm depth of the GR701 fit on my desk?

The case measures 268 mm wide by 639 mm tall by 659 mm deep, so check your desk clearance against those dimensions before ordering.

Which screws or brackets do I use first when installing a 420 mm radiator in the front, and what is the common mistake?

Mount the three included 140 mm PWM fans to the radiator first, then attach the assembly to the front rails; the step often missed is removing the front dust filter before sliding the radiator in.

How do I clean the removable dust filters on the front, top and bottom panels?

Pull each magnetic or slide-out filter panel off, rinse with water or use compressed air, let dry completely, then snap them back into the front, top and bottom mounts.
