I used to own a Phat DS, but well... let's leave it at it got ruined. (I miss Pokemon Dash...)
Since then I have owned two DS Lites, both pink. The first one got a broken hinge while playing Diamond though, and the second one suffered the nearly same fate. However, not too long ago I recently ordered some casing parts online and recased one of the DS lites... sadly though, since my mother seems to have either accidentally hidden away or thrown out the box where I was keeping some of the stuff, I had to also steal some parts from my other DS lite to recase the one (I think I used the screens from different DSs in the end... since I was afraid I terribly mangled one of the ribbon cables, which I'm not sure of. It was sad saying bye to my Pal Pads though). Sadly, the parts also being...3rd party, they didn't fit together perfectly, leaving an ever so small gap between the two pieces used to make up the top screen above the actual screen. But it's fine enough, and works great. (Sadly, me missing some parts... when I put together the other DS Lite again, it's probably gonna be even less perfect than before.)
...and that's how I ended up with a recased DBZ DS Lite with pink buttons.
