There are only 3 mounting holes in Arduino, and not in a tripod configuration. I often mount PC boards on metal standoffs for easier handling and to keep the bottom of the board off any surface that can potentially cause damage, but Arduino is not stable with just the 3 legs.

Why does Arduino only have 3 legs?
