The 300 and 900 are almost exactly the same size: 18" (H) x 18.3" (D) x 8.1" (W) vs 19.4" (H) x 18.4" (D) x 8.1" (W). The 900 just offers a few more fancy bits like the cap on top with the huge fan (making it a touch taller) and a few more ventilation holes.
The specs on the Antec website say the 1200 is supposed to be slightly wider than the others: 22.9" (H) x 20.2" (D) x 8.4" (W).
