Corn Electronics GR701 E-ATX PC case 420 mm radiator four 140 mm fans Transformers edition

Built for big loops

The Corn Electronics GR701 E-ATX chassis fits motherboards up to 12 by 10.9 inches and clears graphics cards up to 460 mm long. Four 140 mm PWM fans come pre-installed, three at the front and one at the rear. Dual 420 mm radiator mounts at the front and top let you run a full custom loop or a pair of large AIOs. A metal GPU holder and 34 mm of cable-routing depth keep heavy builds tidy.

Sustained thermal headroom

With front and top bays each accepting three 140 mm fans or radiators up to 420 mm, the case moves high air volume without spinning fans to extreme speeds. Dust filters on the front, top and bottom stay removable for quick cleaning during long sessions. The 190 mm CPU-cooler ceiling accommodates tower coolers that hold clocks steady under multi-hour workloads. Tempered glass on both sides shows the hardware without restricting flow paths.

Steps up from mid-tower limits

Builders who have hit radiator-length or GPU-length walls in smaller ATX cases gain the extra 120 mm of radiator space and 60 mm of card clearance this frame provides. The nine horizontal plus three vertical expansion slots support multi-GPU or add-in-card arrays that simply will not fit in standard layouts. Buyers who need only a single 240 mm AIO and a mid-range card will find the footprint and 20.8 kg weight excessive for their requirements.
