My PSP 2000 has been in pretty poor shape for a while. It has screen scratches and the battery case is broken. I made all that go away over the course of 3.5 hours of grueling labor and $15 for a new housing on eBay. Now my PSP looks and plays like it's brand new, and got a style upgrade to boot. Check out the pictures below.

I have next to zero electrionics hardware assembly experience. I've built a computer before, but that's child's play compared to all the tiny ribbon cables and connections I had to deal with in the PSP. Still, I'm quite proud of myself. I don't necessarily recommend this to anyone else, however. It's extremely easy to mess something up permanently.
