52 Installing System Components
Figure 3-1. Inside the System
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.
