Introduction
The data compiled in this report is for your reference to facilitate in designing ATX 2.03 compliant chassis that meet the thermal, mechanical, and electrical requirements of Intel motherboards and accompanying processors.

The importance of ATX 2.03 compliant chassis and power supplies lies in the fact that it makes system integration easier and better for everyone. The specification promotes interchangeability, which makes integration/assembly of motherboards (with chassis independent I/O shields) and chassis easier. Overall, this results in lower integration and system costs and also reduced support cost for you. As you can see, ATX 2.03 compliant chassis/power supplies benefit everyone!

Test Configuration
All peripheral bays and add-in card slots were NOT populated for these tests. A heavily loaded configuration will result in lower performance than noted in this test report. This configuration is considered to be the MINIMUM performance required of an ATX chassis.

• *Fluke Hydra Series II Hydra Logger with Hydra Logger 3.0.
• *Hewlett Packard 6632A and 6632B DC power supply for test chamber.
• Custom designed 1/2" Plexiglas temperature chamber.
• *Fluke 79 series II digital multi-meter.
• *Omega .005" diameter *Teflon coated K-type thermocouples

Mechanical Test
The component size was evaluated against the product specification for compliance. The passing criterion is defined as not exceeding the component product specification. The ATX 2.0 board gauge was used to determine compliance with keep-out zones defined by the ATX 2.03 specification section 3.4.
