Yep - the case was pressed aluminium, which cant be returned back to it’s original shape after it has been deformed or bent, so the fitment around thinner spots near the ports and cd drive would always look a bit off after a few years of use.

Thicker aluminium on the unibody is less prone to bending, and much easier to assemble once you’ve overcome the challenges that come with milling, such tooling, optimising the materials usage and recycling the swarm and scrap.
