What is a good fan to put on my case? I want a fan in front placed behind the bezel with a small duct (just for looks) sucking air in, and a fan on top blowing air out, so I need a couple of cheap 90mm fans. I can look at and compare prices on websites on my own but what i really want to know is which fans are most durable/reliable and quietest. Also, where can I buy a duct for my front fan? (i mean a physical store in the US) I think someone said they used base port tubes for the duct, but I dunno where to get that either. I can always buy them from pcmods.com, but Id rather buy them in a real store.
