I received my MPGuino yesterday, and installed it today. It works great, so mad props to DCB.
As to your questions, Aeromodder, it does not come with a case. It is just a circuit board stuck to an LCD.
I can also say that I don't recommend using a reed switch for the speed sensor. It is a bit finiky, and 2 have gone out. I guess they are not intended to be used at high speeds
