I'd contribute to additional perks to have the top panel and both side panels configurable! I plan to use this case for at least 5 years and while my initial build with a 4670k and a gtx 760 is gonna need all the ventilation it can get, as die shrinks continue I hope to drop both my power requirements and need for ventilation over time. Fully sealed up panels, with just a 120mm fan on the bottom for an intake and a 92mm fan for an exhaust would be heaven. Though I'll admit I'm probably in the minority here!
You are not alone my friend
