  • E-ATX motherboard support fits 12 by 10.9 inch boards
  • Dual 420 mm radiator mounts on front and top

What this case is and who it fits

The Corn Electronics GR701 is a full-tower E-ATX chassis built for custom-loop or high-airflow builds. It accepts motherboards up to 12 by 10.9 inches and ships with four 140 mm PWM fans already installed. The white Attack on Titan artwork is UV-printed for durability. Builders who need a compact mid-tower or a lighter case should look elsewhere.

The spec that decides compatibility

Maximum GPU length is 460 mm and CPU cooler height is capped at 190 mm. Both front and top panels support radiators up to 420 mm while the rear takes 120 mm or 140 mm units. Nine horizontal slots plus three vertical positions give flexibility for heavy graphics cards. A 34 mm cable-routing channel keeps wiring tidy behind the motherboard tray.

Installation notes and common pitfalls

Removable dust filters on front, top and bottom simplify cleaning without tools. The metal GPU holder and pre-installed ARGB fan hub reduce extra parts to mount. Front I/O includes USB 3.2 Gen1, USB 3.2 Gen2 Type-C and a USB 4.0 or 3.2 Gen 2x2 Type-C port that may vary by region. At 20.8 kg the case is heavy; plan for two-person handling during assembly.

Questions about this item

How does the 420 mm front radiator limit translate once the case is built?

The front panel accepts radiators up to 420 mm, so a triple 140 mm AIO fits without interfering with the three pre-installed 140 mm PWM fans or the 460 mm GPU clearance.

What does the front USB 4.0 Type C port actually deliver in daily use?

The front I/O includes one USB 4.0 Type C port (or USB 3.2 Gen 2x2 Type C depending on region) giving up to 40 Gbps or 20 Gbps respectively for external SSDs and docks.

Will a standard ATX power supply and the tallest air cooler both fit side by side?

Yes — the case allows PSUs up to 240 mm long and CPU coolers up to 190 mm tall, with 34 mm of cable-management space behind the motherboard tray.
