Saw them on Penn State main campus in June, but last I checked we didn't have street view available yet.

The first thing I do when I get a new case is rip the old fans out and replace them with Yate Loons or Scythes. Stock fans are almost invariably garbage, but fans don't have to be noisy. With the Yates at least (S-Flexes are debatable), the decrease in sound is certainly worth the price.
