I am going to be the middle man here and cut throw most of the poop. Okay reading a lot of news articles on this apple Pc. Apple should have told LTT that was to expensive to repair and offer them discount on a new one witch probably would have soften the blow on both sides. short story
The reason I say this I am quote ting the article in my own words Is it seams there was a lot more damaged then the LTT video had show..
Quote from the article Linus Tech Tips also admit that the logic board and power supply unit needed replacing as well, which suggests the repair process could be pretty complex and pricey.
