Looks like someone in Russia has too much time on their hands.  After being inspired by the movie, they constructed a fully working PC encased in a homemade Wall-E case.  Even though the movie sucked, this case is pure 100% awesomeness.  Made from sheet metal and 18 days of labor, they constructed one of the best case I have seen so far.  Go to the original site for all the photos on how the Wall-E PC was build.
