is it dangerous to paint inside of the case ?I got so much questions about painting the inside of the computer case. Will it damage my motherboard when paint gets too old, starts to fall out and land on the motherboard?
Providing your paint is neither flamable nor conductive, it will not damage the internals of your PC. When it eventually begins to flake off, it will just mean you need to open it up and dust it occasionally
You need to use primer, and great quality metal paint
I'd just generally avoid it, unless you are not too worried about replacing your mobo in a year or two.
