I have the Scout. Totally love it. I am going to add a 120 to the 5.25 bay area for some added cooling. Kinda like what the 900 has. 900 is a nice case, but the lack of behind the mobo tray cable management turns me off of it. Plus the Scout has a black interior. Can't go wrong with that. But really, except for the cable management issue, either case is a great choice.
