Evolv Shift XT
The Expandable ITX Chassis
The Phanteks Evolv Shift XT is a truly unique small form-factor chassis that extends to tailor the cooling performance to your need. Even in its ultra-compact mode there is no compromise on performance with support for powerful hardware such as 324mm long triple-slot GPUs and 72mm tall CPU air coolers. The Evolv Shift XT has the unique capability to extend the height of the chassis to boost the air-cooling performance with two 120 or 140 fans at the top. When fully extended the Evolv Shift XT can house a 240 radiator in the top to cool even the most powerful systems.
Being part of the Phanteks Evolv series, the Evolv Shift XT offer premium build quality and components using thick anodized aluminum panels, PCI-e X16 Gen4 riser cable and USB-C Gen2 front IO. Performance is uncompromised with Ultra-Fine Mesh panels and vented aluminum panels while providing a clean and stylish appearance with the tempered glass infinity mirror.

FAQ
Most products have their product manual in the accessory box or directly printed on the packaging if the installation only contains a few steps. For the latest version, we always recommend checking the online manual, which can be found under the support section of the product page.
Because there are many different GPU sizes, it is always recommended to check the GPU clearance beforehand. If the length of the GPU fits within the clearance numbers, the GPU should fit neatly. This information can be found within the ‘Specifications’ section on the product page.
