I caught wind of this in chat during the All Games Interactive podcast. Someone is modding (not with a chip or anything, but customizing the case) an Xbox 360 in support of breast cancer awareness. Anyone interested can see the work in progress here.
I also imagine there have to be other modded cases that support various causes, much like “support our troops” or perhaps even gay pride. It’s interesting to see that not all case modding has to do with pure tech.
