Easily Haf-932. Best of both worlds in my opinion. If going strictly watercooling then it would be a different story, because both the Haf-932 and Corsair 800D do an amazing job at watercooling. Haf-932 has great air cooling as well as room for watercooling. The fans are large and quiet yet move a good amount of air. You can go 120mm fans as well and they do a great job as well. Have had my Haf-932 for 7 months and its easily the best case I've owned yet. 800D doesn't have that great of air cooling, but it's great with watercooling. In my opinion if it was priced a bit lower it would be a good buy, but for its price range I think I can find a little better.
