I'm now noticed stress cracks on my P3, so I need a new shell. I know the shells are only $60, but to have someone like Hani do it, I'm looking at $100 in labor + $30 shipping. $190 just seems like more than I'm willing to put into this thing at this point. So this brings me to it. How hard is it to do? Should I attempt this myself or is it worth just paying the money for someone to do it? I've build computers before and worked on laptops, and stuff like that. However, I've also tried to work on cell phones and it's gone horribly wrong, so I do want something like that. What can I expect? Any soldering required?
