Hi PaQ, there is also a page here that describes that cooling system and has some pictures:

That works so well to cool the CPU that I would worry quite a bit more about the video card cooling actually rather than the CPU! That's why it is maybe not so great to try and put a super maxed out video card in these little boxes. The one they have along with that box sounds like a good fit though, modern and powerful but not one of the really power hungry ones.

That really sounds like a nice little box, major score! :)
