Build for E-ATX and heavy cooling

The GR701 is a full-tower chassis that accepts E-ATX boards up to 12 by 10.9 inches and fits front or top radiators as large as 420 mm. Four 140 mm PWM fans come pre-installed, a metal GPU holder supports cards to 460 mm, and an ARGB hub handles lighting. Removable dust filters on three sides and 34 mm of cable-routing space keep the interior clean.

Suited for custom-loop builders not for portable

This case targets enthusiasts who want high-capacity liquid cooling, vertical GPU mounting and a themed UV-printed exterior. The 20.8 kg weight and 268 by 639 by 659 mm footprint make it impractical for frequent moves, LAN events or desks with limited depth. Buyers needing a compact or lightweight enclosure should look elsewhere.

Deciding spec front and top 420 mm radiator support

Dual 420 mm radiator clearance is the single figure that determines whether this chassis matches a planned cooling loop. If the build requires that length at both front and top simultaneously the GR701 fits; if the loop uses smaller radiators or air cooling only the extra capacity goes unused.

Questions about this item

Will a 420 mm radiator fit in the front or top without blocking the 140 mm fans?

Both front and top support 420 mm radiators alongside the three pre-installed 140 mm fans, so the radiator mounts without removing them.

How loud are the four pre-installed 140 mm PWM fans under continuous load?

The four 140 mm PWM fans adjust speed automatically; at full load they move more air at lower RPM than smaller fans, keeping noise moderate during all-day operation.

Does the case include the vertical GPU bracket or must I buy it separately?

The metal GPU holder and three additional vertical expansion slots are included, so no extra bracket is needed for vertical mounting.
