The Legs are a Bonus.  Placed in a laundry room that is being remodeled from a flooding.  The previous cabinet was destroyed as it went all the way to the floor and thus sat in the water and soaked it up.  Having the screw in legs to raise off the floor was a great benefit but add the extra benefit that now the cabinet clears the 1.75 floorboard trim and can be flush mounted to the wall to ensure no tipping and extra support.
