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.
