Smallest watercooling system?

[albumleaf]

So I've got the sviking VA4000bws (thermaltake) case. If you're not familar with it, here's a picture. Is it possible to fit a radiator into the back of this case? I know I could fit a bigwater on the outside, but I'd like to keep it contained. Basically I need a radiator the size of a 120mm fan. I'm not sure if I'd actually go through with this, but I'm interested

Can't really see the size of the inside of the case very well from your pic, but if worse comes to worse than you could always mount the radiator to the outside of the case. I've seen a few guys do that. Here is a link to what some other guys did with their watercooled rigs. A lot of good ideas.
