At this point not really. There are paints and paint additives designed to help with heat. These are more for engine parts that get well over 200F. I doubt your card case will ever get that hot so you might be OK as far as heat.
But if the paint doesn't sufficiently bond with the substrate (your case) it can lift and peel. Heat would speed up this process but I just don't have expereince painting PC parts to say one way or the other for sure. In other words you might be effed or you might be just fine, only time will tell.
I would recomend that once you get it painted don't handle it for 24hrs and don't reinstall it for another 24 to be on the safe side. Plus, over the life of the card try to keep from handling it too much. This will keep the chances of the finish crapping out to a minimum.
Now you got me trying to figure out what I want to paint...
