size of atx boards

[Yankee]

I am new at this motherboard upgrade what is the size of different boards

If you're concerned with them fitting your case,, if it's an ATX regardless of the size it will fit. They are all different sizes. You mounting board will have different pre drilled holes to fit the different size boards.

at = 12" x 11-13"

atx= 12" x 9.6"

atx is the most common board you will find these days to be totally honest. you wont have a problem with newer cases and fitting a newer (and some older) boards as well.

Thanks SD, the first time I read that I thought he was concerned with the board fitting on the mounting board for the case, and the screw placement. :D
