Hi everyone. Just took delivery of my new Power Mac G5 Dual 2.7 (new Mac user). Love it so far. However, I have a stupid question; can I use the "handles" (the two arms that extend from the top and bottom of the computer) to lift and move the computer around? They seem quite sturdy, but at the same time the computer weighs about 55lb, so I want to be 100% sure these things are as strong as they are crafted (beautifully, I might add) to look? Thanks.
