You know, I remember having the same idea for a computer case when I was six or seven years old, but I didn't have the right pieces to make one at the time. Anyway, this looks quite neat; kind of funny how the minifigs are all over the place with the control panels. Perhaps these are the guys responsible for all the Windows errors and crashes.

The 5v Technics™ motor doesn't like the 120v power supply.
Do you mean 4.5V? That thing is quite old; they stopped using it in 1990.

It seems that it is possible to run the 9V motors used today at 12V for short periods of time and thus give higher output, and I have heard of some successful attempts with that (there was actually a 12V lego motor in the early 1980s, but it was same as the 4.5v one except that it ran off a wall outlet). I myself have not tried running my lego motors at higher voltages, but that is because I can't spare the money to replace them if they explode.
