The Hydrangea Blue finish is paired with a pre-installed tempered glass panel and an interchangeable perforated front panel.

PCIe 4.0 Riser Sets GPU Limits

A 400 mm PCIe 4.0 riser cable is included for three-way GPU mounting. The cable fixes the GPU interface at PCIe 4.0 and the maximum graphics card length at 415 mm. CPU cooler height is capped at 166 mm and power supply length at 220 mm.

Cooling Capacity Decides the Build

The CTE layout supports up to 14 fans and multiple 420 mm radiators, making it suitable for high-heat configurations. Buyers who need more radiator space or longer GPU clearance should look elsewhere.

Questions about this item

Should I choose the Hydrangea Blue version or one of the other colours for my build?

Hydrangea Blue is one of four colour options — Black, Snow, Racing Green and Hydrangea Blue — so pick the shade that matches your theme; all versions share the same specifications and included riser cable.

What does the 415 mm maximum GPU length mean when I install a graphics card?

Any graphics card up to 415 mm long will fit, and the included 400 mm PCIe 4.0 riser cable lets you mount the GPU vertically or in alternative orientations without exceeding that limit.

How does the PCIe 4.0 riser cable affect the bandwidth available to my GPU?

The supplied 400 mm riser cable is rated for PCIe 4.0, so it supports the full bandwidth of a PCIe 4.0 graphics card when installed in a compatible motherboard slot.
