Yellow Light of Death. I bought new PS3 Slim, and needed to revive the console just long enough to transfer the data over.
The repair went fairly quickly. I'd done a lot of thermal paste application while building PCs over the last 20 years, so there wasn't anything surprising there.
The biggest problem was the blue screw on the hard drive mounting. The head of the screw got stripped by the screwdriver I was using, and I had to use pliers to snap off the other end of the screw to get it out.
The data transfer utility from Sony is not nearly as streamlined as the ifixit guides.
In the end, all goals achieved.
