Aquarium Stand

I was reading a thread posted earlier on how strong the stand for the
aquarium has to be.

I am looking at a bow front 72 gal aquarium by all-glass and was
wondering if I could use a side buffet type cabinet with a bow front
that I saw at Pier One Imports. The cabinet would look great with the
rest of my furniture and match the bow front aquarium.

My question is... how do I check to see if it will be able to hold the
weight of the water, gravel and fish? The cabinet has a solid wood
top, two doors on each side with a shelf in the center. It looks like
something you could safely put a large screen TV on. I put my weight
on it in the store and it seems really sturdy. But I dont want to be
in a position where the tank starts to leak because the cabinet starts
to give way after a while.

Your feedback and insight into this is greatly appreciated.

Thanks in advance.
