Corn Electronics GR701 E-ATX PC case 420 mm dual radiator four 140 mm fans White

Full-tower E-ATX case

The Corn Electronics GR701 is a full-tower chassis built for E-ATX, ATX, Micro-ATX and Mini-ITX motherboards. It ships with four 140 mm PWM fans pre-installed, an ARGB fan hub and a metal GPU holder. Front I/O includes USB 3.2 Gen 1, USB 3.2 Gen 2 Type-C and a USB 4.0 or 3.2 Gen 2x2 Type-C port that may vary by region. Tempered glass covers both side panels.

Suits high-airflow custom-loop builds.

Builders planning dual 420 mm radiators at the front and top, or triple 140 mm fan stacks, will use the full cooling capacity. The 460 mm GPU clearance and 190 mm CPU cooler height handle flagship components. Users who need a smaller footprint, lighter case or fewer drive bays should look elsewhere. The 20.8 kg weight also makes frequent moves impractical.

Standard ATX layout with removable filters and 34

Installation follows a conventional ATX layout with nine horizontal plus three vertical expansion slots. Removable dust filters on front, top and bottom simplify cleaning. The 34 mm cable-management space behind the motherboard tray keeps routing tidy. The only common issue is manoeuvring the heavy chassis into position and aligning the custom UV-printed panels during the initial build.
