There is a few things to do here. For the metal parts clean them up from dirt and grime. Then lightly sand them with a 220 grit sandpaper. Prime metal parts with a spray can of primer....let dry. Spray finish coats with 2 or 3 light coats....2 or 3 coats are better than 1 heavy coat. For the plastic parts they have a different primer for that and it is recommended because it is made to stick to plastic. Don't sand plastic parts just clean....prime then paint. Keep in mind....it might be more cost effective to just go buy a new case....they are not that expensive. Witch ever way you go....Good LuckPainting My PC Case?
remove it completely and spray paint it with a decent quality spray paint! make sure you do it in a ventilated area!
Tape it of and use a spray can.You can get a can extra for plastic.
Use automotive spray paint cans.
