Yes I'm not sure there's room for a rad&fans up top in that case.
Most of the mid tower cases don't really have much room up top for a rad & fans.
Also being a triple 120mm fan rad the PA120.3 is going to require some case modding in any case (at least I don't know of any triple top fan cases)
Then pre-fitted bitumen sound damping material in the R2 might be a real pain to work with.
You could look at the Xclio Windtunnel,

Not the greatest of cases but should make a very good blank canvas for modding.
