Full-tower case for E-ATX builds

The GR701 supports E-ATX boards up to 12 by 10.9 inches plus ATX, Micro-ATX and Mini-ITX. Nine horizontal slots and three additional vertical slots give flexibility for graphics cards up to 460 mm long. Drive mounts include five 2.5-inch bays and two combo bays for 2.5 or 3.5-inch drives. The case ships in an international version and weighs 20.8 kg.

Dual 420 mm radiator mounts and pre-installed fans

Front and top panels each accept radiators up to 420 mm while the rear takes 120 or 140 mm units. Three 140 mm PWM fans come fitted at the front and one at the rear, all connected to an integrated ARGB fan hub. A metal GPU holder braces heavy cards and removable dust filters sit at front, top and bottom. Front I/O provides a headphone jack, four USB 3.2 Gen 1 ports, one USB 3.2 Gen 2 Type-C and a region-dependent USB 4.0 or USB 3.2 Gen 2x2 Type-C port plus LED control and reset buttons.

Tempered glass panels and cable space

Left and right tempered glass side panels showcase the interior while 34 mm of cable-management depth keeps routing tidy. The 60 W fast-charging port on the front panel powers devices quickly. Maximum CPU cooler height is 190 mm and power supplies up to 240 mm deep fit without issue. Builders needing more than nine expansion slots or a second GPU in a non-vertical layout will need a different chassis.

Questions about this item

Does the front USB 3.2 Gen 2x2 Type-C port actually deliver 20 Gbit/s, or is it limited by the motherboard header?

The port is rated for USB 3.2 Gen 2x2 speeds; actual throughput depends on the motherboard header you connect it to.

Will a 420 mm radiator fit in the front without blocking the three pre-installed 140 mm fans?

Yes, the front supports a 420 mm radiator alongside the three 140 mm fans; the fans can be repositioned or removed if clearance is tight.

How do you power the ARGB lighting on the four pre-installed PWM fans?

Connect the case's ARGB fan hub to a 5 V addressable RGB header on the motherboard; the hub then powers the lighting for all four fans.
