I bought a HAF 932 BE (Black Edition) last month, to replace my 690II Advanced.
The 690II was, and is, a nice case, but as I recently acquired a second 480 to run in SLI with the first one, I had to get a bigger case. This was due to the triple-slot coolers I had on both 480's. The 932 has an optional top-mount ps spot, which gave me enough clearance for the 480's and their custom coolers:
Aside from the huge space increase, the 932 is a much sturdier case than the 690II, which is made from thinner-gauge steel than the 932. More fan options, room for water-cooling, etc.
As for your original question, the HAF 932 would be ideal as it has the room for two cards and great airflow for your setup.
By the way, I have no issues with the front panel. If you ever did have any problems, CM would send you the replacement part to fix it. But this problem has been fixed for quite a while now.Edited by DerComissar - 5/23/11 at 11:26am
