Expansion slots (such as PCI Express x16, x1, and legacy PCI) allow you to add graphics cards, network adapters, and other peripherals to your system. Having more and varied slots increases upgrade potential and system flexibility. For instance, the Dell OptiPlex 3020 offers PCI Express x16 and x1 slots for adding GPUs and expansion cards, while the Gigabyte Z390 includes multi-GPU support for gaming or professional use. The availability of different slot types ensures you can customize your motherboard according to your needs.
