The right tool for the job
When I had to do an unplanned dissection of an overheating laptop, I was pleasantly surprised that I already had the perfect tool for cracking the case in a watchmakers' tool kit. (It's the yellow tool in the photo, though that's not the actual set I have, which seems to be unavailable.) I hoped it had a cool evocative name, but it just seems to be a "watch case opener" or a "push-type opener". Instead of anxiously pulling on the plastic, trying to find the right balance between pulling the connectors free and snapping them right off, you can just run it along the crack and pop the parts free. Whoever invented this deserves a medal.
