So I just booted up my new $799 1TB standard 2012 Mac Mini. I'm familiar with hard drive noise, but this sounds especially treble-y/clicky, almost like a fine sand grinding. The drive checks out in smart, etc. I know there have been some posts of this noise but many of them feature another deeper noise or clunking. I haven't experienced this, but the normal operational noise of the hard drive is especially annoying, sounding like grains of sand caught in a small grinder. Is there something about this case design that may be amplifying the noise? I know it's sitting right on the removable cover, not having feet or what not and I'm wondering if this is amping the noise. Also, should I consider bringing it to apple or thinking about exchanging it, or is audible hard drive noise common in these 5200 drive mac mini's? Any help is very much appreciated! I don't want to set up all my data on this machine until I know I'm keeping it!
