3dcool cases are decent, but those kinds of mods are easily done by one's self, and can be done with a better case than hte InWin Q500 and be done to have more airflow.
Not to mention that 3dcool cases are overpriced.
My vote for the best, an Addtronics 7986A(the one above mentioned with teh 120mm intake fan). Second best, probably a coolermaster atc-200, but the cost is ridiculous.
As far as the 7237 goes, its my personal favorite for low cost Mid-Tower ATX(and my favorite midtower ATX, and the case I currently use) but it isn't the best case around....
