Cooler Master Centurion 540 mATX Case
 

For a cool $44 USD, the Centurion 540 is a very good case for the money. You won't find a PSU with the case at that price, let alone the fans we just mentioned, but we think this is one of the easiest MicroATX cases to work with. It offers excellent cooling potential, it's very easy to work with and looks pretty damn slick to boot.
