It would be great if there was some way to attach handles to the underlying frame of a U2-UFO so that you could carry it more easily, but unfortunately, there isn't. You could drill holes in the top cover and mount two handles pointing vertically, but it wouldn't look very nice, and if you tried to lift the case, the weight would be borne by the nine thumbscrews, which doesn't seem robust to me.
That said, mounting these mighty handles horizontally at the top of the the front and back panels is a useful upgrade. It certainly makes it much easier to manipulate the giant cube. To my eye, they look great, and even serve to protect the front of the machine from collision damage.
