I am getting a Chemning Silver AX-01 case soon. My mother is an artist (and has nothing to do), and I was wondering would it be safe for her to paint small designs or decals on the outside of the case? If so, is there a specific type of paint that I should have her use? Also I am getting a DVD drive and I think I would like the face to be black or silver instead of beige, is this safe as well? Thanks!
