This article from AnandTech gives an exciting, thorough first look at the BTX form factor. Read the article, it’s great, but I can also sum up some of the points it makes.

Here’s the quick and dirty BTX info:

• there will be three BTX sizes, BTX, microBTX and picoBTX
• thermal design considerations drove a lot of layout changes
• PCI express x16 will be the likely graphics card slot of choice
• ATX power supplies will be electrically, but not physically compatible with BTX PSUs.
• This form factor should be introduced in 2004

For the complete story, as usual, count on formfactors.org for the complete spec.
