As far as I can see, the only difference between ATX and EATX is about 50mm extra width (990FX-UD7 is 305x263, Z68-UD7 is 305x244, EATX spec is 305x330?) - or are the screw holes different? They don't look like they are, just seems to be extra PCB past where the screw holes are on the right hand...
