Well Version 3.0 is usually backward compatible so it should work in a 2.0 slot. That shouldn't be a problem. And in regards to the ATX socket that shouldn't be a problem either so long as the Graphics card is only a single slot card. You have to take in to account that with these back to front motherboards the card will also be the opposite way up than in a normal system (Fan of the graphics card upwards, instead of downwards)
Like i said my Wife's takes a single slot 9500GT without a problem. The only difference being is that her motherboards ATX socket is away from the PCI-E port. But with your board they must of taken in to account that someone would want to put a Graphics card in there otherwise they wouldn't have put a PCI-E slot on there in the first place.
I'd be tempted to try another card in there to make sure if you have one spare. Or you know someone that has one you could try.
By the way. Which exact GTX 640 do you have in mind?
