2) Clean it out (if not new) because chances are it smells alot and/or it's dusty.
3) Go to a foam store and get measurements for your case(bring it with you, and some models). The foam that you want has cones on it and it looks best if it is black/dark grey. Usually the foam is order and might take a week. The foam that I bought costed about $12.00 CDN.
4) Once you have the foam, insert it into the case. If it does not fit good, take it back,
5)[Optional] Put a name tag and/or funny bumper sticker on it.
Sorry, don't have any pics.
