Hard disk drive carriers

You can install additional hard disk drives in these carriers inside your computer. If you have ATA hard disk drives, you can install up to two drives in a single U-shaped carrier. If your computer came with one or more SCSI hard disk drives, you can install up to three SCSI drives in the drive carriers.

AirPort Card connector

Connects an AirPort Card, which allows your computer to communicate with a wireless network.

PCI expansion slots

You can install PCI cards in these slots to expand your computer’s capabilities. For example, you can install a SCSI PCI card and then connect and use SCSI devices such as scanners, hard disk drives, and Zip drives.

AGP graphics slot

Connects your AGP graphics card, which provides fast graphics processing power to your monitor. You can connect a monitor that has an Apple Display Connector or a standard VGA connector.

SDRAM slots

You can install additional memory in your computer by inserting up to 3 DRAM DIMMs in the memory slots. You can expand your computer’s memory up to 1536 MB (1.5 GB).

Battery

Your computer uses a battery that you rarely replace. If you find that your computer is having trouble starting up, or that the system date and time are frequently incorrect, you may need to replace the battery. For more information, see “Replacing the Battery” on page 71.
