This used to be the case, but tank makers are getting away from that. Newly constructed tanks come with cellular support pads for the whole base of the tank to help distribute the weight throughout the entire bottom glass.

The tank he has is not rimless. The only portion of the glass that will be making contact with the stand is the perimeter of the pane that is attached to the bottom rim. I have almost the same tank and I can put my finger between the center bracing and the glass itself.
