Do metal boxes need to be grounded?

I changed out a variable fan switch that is mounted in a four ganged metal box situation. There is one outlet and two 3way light switches in the ganged boxes along with the variable fan control. Found that the devices all were grounded but there was not a ground wire to the metal box. Is it a requirement to have the box itself grounded?
