I just got the Antec 300 steel computer case in the mail yesterday and I discovered that it has a small dent (about an inch long)on the top-left portion of the left side panel. I am going to mod the case (paint the interior and add a window) and I would like to know some ways I could remove the dent with out damaging the paint on the outside. This is the only dent I have found and I don't think it is bad enough to make a phone call to Antec for a replacement.
Take a can of air duster, spray it. keep sraying so it cools it down. Then take a hair drier and blow it on the dent on max. The cooling then rapid expansion should pop it back.
Ether and fire..
Nah, just kidding. Don't try that.
