I have a cracked a nice Power Stone 2 that is near mint apart from the cracked case. I have other near mind Dreamcast cases, so I was wondering if there is an easy way to replace this case with the better one. My main concern is back cover art and the spine, basically the stuff you normally couldn't get to. Everyone always talks about how jewel cases are easy to replace, but I'm a noob with this stuff so could someone explain it to me? Thank you in advanced.
