The system board holds the system's control circuitry and other electronic components. The processor
and memory are installed directly on the system board. Using a riser card, the system can accommodate
two expansion cards. The peripheral bays provide space for up to two hard drives and an optional optical
drive. Power is supplied to the system board and drives through one nonredundant power supply.

The system is enclosed by an optional bezel and cover. To upgrade or troubleshoot the system, remove
the bezel and cover.
