No solution here, just some bad experience.
I had a long battle last summer with black painted case. I learned with DOT4 brake fluid you can remove some specific type, but it was not very efficient on this particular paint. It was good on some parts of golden drive bay covers. It's also nasty stuff to work with, not recommended.
Gasket remover spray also works on some level, but it might damage plastics so I used it only on metal parts. Also nasty fumes, not recommended.
In addition I tried some soap mixtures but no avail.
Soda blaster was the most effective experiment. Still I could not remove the paint completely, paint was like melted into the plastic.
Eventually I got tired and accepted my failure. Just good sanding with fine paper and new matt white spray paint was my final solution.
