Well for some pictures you can see my upgraded build here:
From Q6600 to Sandy Bridge
As for impressions, well there is a lot of space inside and is quite easy to work with. One thing is that the back side has almost not enough room for all the cables to get hidden. But that said the cable routing options are excellent. As for airflow it is much better than my previous case but I still think this would be better suited for watercooling. Of course you can improve the airflow be removing drive cages or re-arranging them as I did.
