Welcome to the forums.
I am not familiar with your case, however someone will almost certainly have watercooled one in the gallery in the case section. You should decide whether you're willing to cut up your case or to mount radiators external to it. These will make life easier, but its fair enough if you're reluctant. Radiators are the only large component really, so if you can fit these the rest shouldn't be a problem.
Next, why do you want to water cool? Can you swing a large enough budget to do it well, or are you willing to go second hand? Below £100 or so it's probably best to stick with air cooling.
