Mini-ITX is a standard that defines the size of motherboards and, consequently, the computer cases designed for them. A Mini-ITX format motherboard has exact dimensions of 17 x 17 centimeters, making it one of the smallest commonly available formats for building a desktop computer. A computer case with Mini-ITX support is thus designed to accommodate this small board, resulting in a very compact build. This type of case is sought after by users who want to save desk space, are building a living room computer as a multimedia center, or require an easily portable machine. The small dimensions bring certain limitations. Internal space is limited, meaning fewer bays for hard drives and other expansion components. Motherboards of this format usually offer only one expansion slot, referred to as PCIe, which is most commonly occupied by a graphics card. When choosing components such as a CPU cooler or power supply, it is necessary to pay attention to their dimensions to ensure they fit into the case. Therefore, special smaller power supplies, such as the "SFX" format, are often used instead of standard large ATX power supplies.
