hehe...I have to say it :
Q: Quietest case at Newegg?
A: Any case that does not have any fans
Come on, you know you want to give me mad credit
Now if you are asking what case is the quietest with the PSU that comes with it, then you want to look at the Antec's, or just be prepared to pull out the PSU and replace it (which would probably be a good thing to do anyway, if its not Antex or Enermax). From my experience the Antec SmartPower PSU's are one of the most quiet PSU's out there, followed by the TruePower and then Enermax.
