Did this repair last night and my first gen PS3 is back up and running, plus i got my friend's game out that's been in there for almost a year! The toughest parts for me were the top cover (step 6) and removing the PRAM battery (step 34). Those two things did NOT want to budge!! I kept feeling like i was going to break them. Removing/re-applying the paste took a while too, as i was extra paranoid about getting the layer of thermal paste just right. All in all, it was a good experience. Easy to follow guide and great tools. Hope my repair will last!
