Small case doesn't mean bad cooling. Of course i dont know the case you speak of, but perhaps you could do some modifications to it and add some fans. Make sure there is an air flow from front to rear and you can't go wrong.
As for the actual question, well, if this is a picture of what it looks inside:
it looks like it is an a standard mATX but i cannot be sure. The usb-kind-of-bracket just above the gfx card and the I/O shield will probably not fit.
Still, i do see 2 3pin fan connectors on the board (or i think i see 2, 1 is there for sure) near the ram. Now the front cover of the case seems to be designed to accomodate a 120mm fan and you can see the 80mm fan space in the rear. Pull from front, exhaust from rear, you will be fine.
