Built for high-capacity E-ATX builds

The Corn Electronics GR701 One Piece Ace is a full-tower case designed for E-ATX motherboards up to 12 by 10.9 inches, plus ATX, Micro-ATX and Mini-ITX. It includes four pre-installed 140 mm PWM fans, a metal GPU holder and an ARGB fan hub. Seven drive bays support 2.5 and 3.5 inch storage. Front I/O provides headphone and microphone jacks, four USB 3.2 Gen 1 ports, one USB 3.2 Gen 2 Type-C and a USB 4.0 or USB 3.2 Gen 2x2 Type-C port depending on region.

Dual 420 mm radiator support and heavy airflow

Front and top mounts each accept radiators up to 420 mm, while the rear takes 120 mm or 140 mm units. Three 140 mm fans at the front and one at the rear move air through removable dust filters on front, top and bottom. The steel structure weighs 20.8 kg and offers 34 mm of cable-management space behind the motherboard tray. Tempered glass panels on both sides display the interior.

Replaces smaller towers that limit radiator length

Builders moving up from mid-tower cases gain room for 420 mm radiators on two faces, a 460 mm graphics card and a 240 mm power supply. The vertical GPU bracket adds three extra expansion slots. Buyers who need a lighter case for frequent moves or who have desk depth under 659 mm should consider a more compact chassis.

Questions about this item

How do I install the 420 mm radiator at the front and what step do builders often miss?

Mount the 420 mm radiator to the front bracket using the included fans, then route the tubes toward the rear so they clear the 460 mm GPU limit and the 190 mm CPU cooler height.

Which dust filters need regular cleaning and how are they accessed?

Removable filters sit at the front, top, and bottom; pull each magnetic frame outward, rinse with water, dry fully, then snap back into place.

What thermal limit appears first when the 360 mm top radiator runs at full load for hours?

The 190 mm CPU cooler height restriction and 34 mm cable management depth limit airflow around the VRM heatsinks before the radiator itself saturates.
