Has your 20" iMac Alu a "bleeding light glow" at the bottom/top of the screen?

I've noticed that my 20 inch iMac Alu glows at the bottom and the top of the screen when displaying a black/very dark picture (for example when looking at the "flurry" screen saver). It's not so bad, and it is only visible when the screen is showing a very dark one-coloured-image.

I'm curious to know if this is a common issue, and if anyone else has the same phenomen on their iMacs.

Another thing I have noticed is that my machine is giving a pulsing low-frequency sound when connected to an external harddrive. It's quite irritating, but I read about another guy with the same issue, maybe all machines are like that?

all my macs (mbp, imac, 30'' acd) have some bleeding at the bottom so I don't think its that unusual.
