The Antec 1200 has 3x 120mm intake (included), 2x rear exaust (included), 1x 200mm top exaust (included). There is a space for a side intake 120mm (which seems to have perfect airflow for the GPU's and not a disruption at all. You also have the option of a 120mm intake fan midcase, which works wonderfully in the first set of hd bays (there are three sets of bays that each hold 3 3.5" hd's if you want, each one has one of the intake fans on it), and is directly lined up wiht my ram, ram temps dropped about 3C when I added it running full power.
