Hi everyone, I'd like to ask about 2 issues that are so slight that they may not be issues at all but I'd like some affirmation. (I have a 27" Core 2 Duo iMac) 1) When in Sleep, the iMac produces a very slight buzzing sound that's audible if you place your ear near the horizontal slit that runs across the top of the monitor in the back. Could anyone check to see if theirs is like that too? (I don't know if this sound occurs during operation since other sounds are also present.) 2) Again, occurring from that horizontal slit at the back of the iMac, there's a slight smell, that I'm only able to describe as the smell of warm electronics. Is that also present in anyone else's iMac. I've been using latops for almost 10 years, so I don't recall what is normal for desktops. (The iMac is warm to the touch, but I'm certain that much is very normal.) Thank you!
