PCIe slots in a desktop PC can host far more than just a GPU. USB expansion cards solve port exhaustion on motherboards with limited I/O. PCIe-to-NVMe adapters add extra M.2 slots for budget boards lacking storage options. Network interface cards (NICs) can upgrade slow onboard Ethernet or add Wi-Fi. For home lab users, HBA cards enable cheap SAS drive connectivity, and IPMI cards allow remote BIOS and video access for troubleshooting.
