I received my new iMac the other day. It's great! No more high pitch sound!
So my previous iMac definitely had a problem. Also, I noticed that the "chin" and the top left section (where hard drive is located) no longer vibrates (it was on the other one and I thought it was just normal).
I also noticed that this new iMac is using a Wester Digital (vs Seagate) hard drive. I heard that WDs are quieter than Seagates (at least their recent drives). So that may have been the problem.
Overall I'm VERY happy!
(BTW, it took about a week for my iMac to arrive at their warehouse and another 2-3 days for the new iMac to arrive at my house.)
