iMac making this rattling sound. Here's the audio. Why?
Here is the audio recording: http://bit.ly/SjOdbk
iMac, OS X Mountain Lion (10.8.2)
I don't here anything at all, of course I'm close to deaf, but turned the volume up to max!?

Run the Apple Hardware test. It could be your Hard drive or possibly one of the fans.
