It depends on the size and weight of your robot. Just try and plan out where your parts go to get general dimensions. On that robot, I used .25" HDPE, and I think it was 1' x 1' dimensions. I used a bandsaw to cut it, but a common handheld hack saw can cut HDPE really fast too.

This tutorial can help you select a motor:

If you are ever unsure, get the motor that has more torque and lower rpm.

if you have plans about opening your monitor, WEAR SAFETY GLOVES AND GLASSES!!!
those bastards contain like 25 000V (yep, 25 thousand Volts).
and becarefull, i always unsolder the big capacitator and the flyback transistor, aswell as remove the monitor itself...
but it might be another better way, anyone know?
