Introduction
Thank you for attending the ATX Plugfest II in October. The data complied in this report is for your reference to help facilitate you in designing ATX 2.01 compliant chassis.

The importance of ATX 2.01 compliant chassis and power supplies lies in the fact that it makes ATX 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 2.01 compliant chassis / power supplies benefits everyone !
