SO-DIMM slots for system memory modules

There are two SO-DIMM slots on the motherboard. Each slot allows you to
connect one SO-DIMM memory module up to 2 Gbytes in size. The pinout for
the SO-DIMM slot is available at the website of the Joint Electron Device
Engineering Council (JEDEC): http://www.jedec.org.

SATA connectors for mass storage devices

There are two 7-pin SATA male connectors for mass storage devices on the
motherboard: port 0 on the left and port 1 on the right (when facing the front
panel). The pinout for the SATA connector is available at the website of the Serial
ATA International Organization, http://www.sata-io.org.

Power supply connectors for peripheral devices (fans)

There are two 3-pin power supply male connectors for peripheral devices on the
motherboard.
The following are the specifications for each pin on the fan connector:
