There's also how the Atari Falcon 030 had an unused microbox design, that Sony ultimately used when designing the original PS2.

Did you know the PS2 case design was licensed from Atari? It was originally intended for an unreleased Falcon computer.

The original damage from light causes degraded or free bromides throughout the case from the fire retardants. Retr0Bright only takes these away from the surface layer. However these bromides can migrate fairly freely through the polymer. They don't need light to do this. Migration is probably accelerated in hot conditions. These pre-existing bromines from the original damage migrate to the top and within a few years the surface is yellowed again. The rate of the regression depends on the inital extent of yellowing (the more yellowed, the more bromides down deep), heat exposure and the nature/quality of the plastics.

Our experiments showed that it is not recommended to use RetrObright or Hydrogen Peroxide on the types of plastic we studied. As you can see photos taken through the microscope, both products caused an etching of the surface, which was also visible to the naked eye. After purification with hydrogen peroxide on polymethyl methacrylate (PMMA), a clear cracking could be seen in the area where the solution was applied. Polyvinyl chloride (PVC), on the other hand, became food and the photograph shows how the soap-like gel has eaten a bubble-like pattern in the surface of the material.
