The Blarg of Fosnez

As I couldn't really find any instructions on how to do this, here's what I've discovered. Also, forgive how filthy it is, clearly I don't turn it upside down enough... Remove the three screws indicated with yellow arrows. Two of these are normal philips screws (under the foot pads, these can be removed with a flat screwdriver), the other is a small hex screw. Then, there are 4 screws that secure the circut board down And then, yup... that's a circuit board.
