Balanced Technology eXtended (BTX) Form Factor - The Future of Cases & Motherboardsby Anand Lal Shimpi on September 18, 2003 12:34 PM EST

For years we've bought motherboards and installed them in cases based on the ATX (Advanced Technology eXtended) form factor. The move to ATX brought huge improvements over the previous AT standard not only in the cases, but in power supplies as well.
As is made evident by the proliferation of Small Form Factor (SFF) machines into the market, the need for a smaller, quieter successor to ATX has been building over the past 8 years. A couple of IDFs ago, Intel announced their development of the successor to ATX, which was codenamed Big Water. At the Fall 2003 Intel Developer Forum, Intel officially branded Big Water as the Balanced Technology eXtended form factor - or BTX for short.
With BTX motherboards and cases due out next year, it's time to start learning about what's changed with BTX and, what improvements the specification offers over ATX.
