Rosewill Thor V2. Quietest case and the stock fans are great. It's very "open" for airflow and with the large fans, you can have some excellent airflow with low noise. When I'm not pushing my CPU to the limits, my fans are on LOW (600rpm for CPU) while the case fans are at max and I hear the PSU fan more than the giant 230mms.
As much as the R4 is cheaper, I do prefer the Corsair 550D. In my opinion it looks a lot nicer, has 4 5.25 bays instead of just 2, and in the anandtech review, is a quieter case although a little warmer.
To be honest, MOST(not all) people actually don't need more than 2 optical drives. The HDD cages can be removed to install an H100, not sure about P/P.
Having 4 optical bays allows for two optical drives/ or a card reader/fan controller etc and room for a 5.25 reservoir if anyone ever want to go down that route.
Personally I can see 4 5.25 bays being a lot more useful then 10+ HDD bays considering most people will only have 1 HDD, 1 SSD, or maybe at most 2 HDD's and 1 SSD.
