All I know is that if you don't ground it and rest your forehead against the frame you get a nice little tingle going on I live in an old apartment where the only grounded outlets are in the kitchen so I don't have much choice in the matter.
UM2 power questions : do I need to ground the board ?
ha ha ... the way you say it makes me believe you actually do this a few times day

a bit late... I know.... easy to measure..... on the original UM2 powerblock the outerring of the plug is indeed directly connected to the mains ground..
