theyre not cases, they are motherboards. btx is basicly the same as atx, only the slots are on the top and the cpu is on the bottom. just like an upside-down atx board. the cases just support that form factor. yeah and google would have been really helpful too :D

BTX allows better air flow.

The redesign of the board layout was done in order to improve airflow through the system; moving the CPU to the "front" of the case allows it to be right next to the intake fan, giving it the coolest air out of any component in the system.

Because of the different position of the components BTX motherboards you will need a BTX case. You will also need a BTX PSU because an ATX PSU will not work with a BTX board.

Because of the increasingly speed (and heat) of CPUs this design will become more and more popular.

About the best info you can get :)


The addition of the PicoBTX standard should be nice. While it is not much smaller than a mATX, it is still smaller (well kind .. less width more depth).
