The HAF 932 is a much better case. The Antec 1200 is much smaller, it has worse cable management, no CPU retention plate access hole, worse potential airflow but better stock airflow and it is much worse for water cooling. The HAF 932 supports two PSUs and is easier to work with due to its size, CPU retention plate access hole and drive bay design.
The only advantages the Antec 1200 has are an all black finish (debatable), dust filters (easy to make your own or just buy your own), fan speed control and again better stock airflow. Here is a video review on both cases.

I really don't see why anyone would buy any Antec case at this moment, other than looks if they like it. But I don't really like the look of any Antec case myself. Antec is way behind in their case lineup. The Dark Fleet is just an updated Antec 1200 that still falls short in many categories.
