Thanks Cronos, I am at the last step before I start my first build, so just trying to tie up some loose ends. Thanks again for the advice.
I actually have both the 922 and the 912. The 922 is much more roomy inside and as such it is a BIG case. The 922 comes with two 200mm fans one on top and one in front which moves lots of air quietly. The 912 however does have better drive bay options, it has 2.5" drive holder the 922 does not AND the 912 you can remove part of the drive bay behind the front fan so there is direct airflow with nothing in the way between front. Also the 912 does not come with 200mm fans just 120 back and 120 front but you can order 200mm fans if thats what you want. You almost have to remove the extra drive cage if you have long cards which isn't that big a deal unless you have tons of HDDs.
I really prefer my 922 for the roominess but I wish I could have the drive cage setup that the 912 has.
