What does that ATX mean on the front of a computer case?
ATX is an architecture standard that was developed by Intel in 1995 as the first major change in computer case and motherboard design in many years. Due to the unregulated Baby AT motherboard market and the overly obsolete AT motherboard architecture, Intel announced the Extended AT motherboard architecture, known as the ATX (Advanced Technology Extended) motherboard standard, in January 9
5. ATX replaced the AT motherboard specification as the default motherboard specification for newer computer systems.
This new standard is the first of its kind in the United States. ATX solves the problems that have plagued computer assemblers in the past with the AT specification.
This standard is supported by the world's major motherboard manufacturers and is now the most widely used industry standard; ATX version 2.01 was introduced in February 1997; most of the motherboards used in popular PCs in 2010 are ATX boards.
In 2003, Intel released the new BTX motherboard specification as an alternative to ATX. Despite this, the ATX specification remains the most prevalent motherboard specification for assembled computers until today.
