Mainboard Form-Factor
This board is designed with Micro-ATX form factor - the latest industry standard
for chassis design. The Micro-ATX form factor is essentially a Baby-AT
baseboard rotated 90 degrees within the chassis enclosure and a new mounting
configuration for the power supply. With these changes the processor is
relocated away from the expansion slots, allowing them all to hold full length add-
in cards. Micro-ATX defines a double height aperture to the rear of the chassis
which can be used to host a wide range of onboard I/O. Only the size and
position of this aperture is defined, allowing PC manufacturers to add new I/O
features (e.g.; TV input, TV output, joystick, modem, LAN, audio, etc.) to
systems. This will help systems integrators differentiate their products in the
marketplace, and better meet your needs.
•
By integrating more I/O down onto the board and better positioning the hard
drive and floppy connectors material cost of cables and add-in cards is
reduced.
• By reducing the number of cables and components in the system, manufac-
turing time and inventory holding costs are reduced and reliability will
increase.
• By using an optimized power supply, it's possible to reduce cooling costs
and lower acoustical noise. An ATX power supply, which has a side-
mounted fan, allows direct cooling of the processor and add-in cards making
a secondary fan or active heatsink unnecessary in most system applications.
