DigiMac Pro Mount from INOVATIV

I just came across this Mac Pro mount system from INOVATIV. The mount is meant to be used along with INOVATIV's digital tech plate system but a part of me can't seem to get past the fact that mounting such a heavy machine only by the lip of the aluminum curve is good for the machine. It's not right? And even if it is, are people really bringing Mac Pro's around like this? I need more photos of this being used in the wild.
