The innovation of the Silverstone Fortress FTZ01 is the use of a GPU adapter in the form of a PCIe riser card, which allows for the installation of a full-sized dual-slot gaming graphics card measuring up to 33 cm in length and a maximum width of 14.9 cm at a 90-degree angle, parallel to the motherboard. While other cases of similar format often reach their limits with mid-range graphics cards, Silverstone ensures top computing power here, demonstrating that the Fortress FTZ01 is in a class of its own. The GPU holder also accommodates two 2.5-inch drives, which can be conveniently installed outside the case along with the graphics card and the optical slim-slot drive. This remarkably original design allows a suitably equipped Fortress FTZ01, in combination with a powerful processor, to deliver truly divine performance.
