Speaker assemblies — stereo speakers are located at the front of the LCD unit and below
the LCD panel. Cables connect the speakers to the operations board.

board shield; includes the processor, SO-DIMM socket, Mini-PCI socket, PC Card bay, two
USB ports, microphone jack, line-in port, line-out port, and cable connectors (see "System

Hard drive assembly — located at the rear of the LCD unit below the system board. The
hard drive is connected to the system board by a single signal and power ribbon cable. A

design allows for easy movement of the LCD unit. It also provides an area for interface
