Macbook Pro Melted Its Own Casing - Expert eyes needed on this photo please of my macbook pro

This is a 2008 15" Macbook Pro.

At the genius bar I pointed out that the computer was so hot I could barely hold it, so hot the computer had warped it's own plastic casing where it connects to the power source.

So the genius guy took it in the back, opened it up, diagnosed a fried logic board and said "For $310 we'll fix up anything in the computer, you'll get it back good as new." In 2010 the logic board also fried and was replaced, and the heat cooling system was then replaced - looks like the same issue all over again.

So I took it home to get the data off the hard drive, but when I brought it back a few days ago, the new 'genius' made a different diagnosis.

Without barely looking at it, without taking it in the back, and without listening to or believing anything I told him, the Genius Bar are calling this impact damage - overriding the previous genius's assessment.

How can the perfectly symmetrical ripple wave in the plastic which goes top to bottom through a half inch of plastic be created by impact damage? And that the plastic piece below is not warped would mean I would have had to have removed the bottom piece of the computer, dropped it, then put it back on, in order for it to not be warped like its top half.

Are there any expert eyes out there who have an opinion on this keeping in mind the symptoms?

Additionally when the computer was its hottest, the trackpad would not click. The plastic must have expanded from the heat. So it would click, but only if I pressed really really hard. Doing this one day the plastic on the trackpad actually shattered from clicking it. But the shattering must have removed the surface pressure from the expanded plastic and therefore the trackpad became fully functional again in its shattered state and that's how I've been using it for quite some time.

I really appreciate any expert support from the community here if you disagree with the 2nd geniuses because I am complaining through official channels. I do not want to pay extra for damage the computer did to itself. Especially when this is the 2nd time the logic board fried on this computer.

I am someone who has owned apple's first everything since the 80's, and have worked on two Apple commercials myself. I'm currently typing this post from a PC... Does Apple want to satisfy its customers anymore or what?

I never did get a feeback solicitation emailed about this appointment either, I wonder why.
