I have the HAF 932 for one of my systems. It is a huge beast. Ventilation, airflow, and cooling are excellent with just the stock case fans. Plenty of room inside the case. Cable management is excellent.
Between the Antec 1200 and Cooler Master HAF 932, I'd pick the HAF 932. Two other options would be the Cooler Master ATCS 840 or the Lian-Li PC-P80B Armoursuit, but if you're going to use watercooling, the Corsair Obsidian 800D is a great choice.
