Well i was looking for a case to house my Raspberry/Poison (im using it as a dropbox pentest tool) PI and wanted to make something my self. I was thinking along the lines of a large phone (On charge) or a hand held games system again posed as on charge. Then i came up with the idea of fitting it inside am old Game&Watch i had. The dimensions are almost perfect for modding, Apart from an over cut, i tried to fit it the other way round first then released it would be better upside down in the case.
I know some of the cuts are rough but i did this all with a swiss army knife ^_^ with a Dremel it could be a nice job.
Would also make a nice retro case for running some old nes games
