I can appreciate your plight. I am on my 4th Macbook Pro, not counting one replacement which couldn't boot up at the store. I have had dead pixels in the center of the screen, bad VRAM, a bad right speaker and strange hard drive sound, and a failed logic board/searing heat. All of them had the CPU whine to some extent. This one seems like it will make it, as it has none of those problems, and has a later serial number (W8612). I do know how annoying the bad speaker was. I had seen on the internet that people were having problems with the quality of the right speaker, but I knew it couldn't be normal. Good luck!
