if u wonder about the compacity, you may want to consider:
Thermaltake iCage 5.25IN To 3.5IN Aluminum Drive Bay Convertor W/ 120MM Blue LED Fan.

The only disadvantage of the Thermaltake iCage is that it can only hold 3 HD instead of 4. But it should privide better airflow considering the front case design behind the fan.
