Back Panel Connectors
The motherboard external IO connectors are attached to a metallic I/O shield. This shield
serves several purposes:
It protects the sensitive motherboard from any external EMC interference.
It stops the computer from interfering with other electrical devices.
It allows the motherboard to be easily upgraded in the future without having to resort
to buying a whole new case. Simply change the I/O shield to match the motherboard.
The I/O shield provides external access to PS/2 mouse/keyboard connectors as well as
the USB ports, LAN Port, audio connectors, VGA and HDMI ports.
