What form factor reduces the total cost of a system by reducing the number of expansion slots and allows for a smaller case size?

The form factor that reduces the total cost of a system by minimizing the number of expansion slots and enabling a smaller case size is the Mini-ITX. This compact design is ideal for building budget-friendly and space-efficient systems, particularly for Home Theater PCs or compact desktops. By integrating components more closely and limiting expansion options, Mini-ITX boards help lower manufacturing and assembly costs while maintaining essential functionality.
