How to remove the stand's center brace

[Casey8]

I have a stand for a 40 gallon breeder tank that I want to put a long sump about 36" long in there, but I have to remove the center brace on the top of the stand which is right underneath the tank. I don't see any nails, but I only see the glue. I would like to know if I can saw it apart ? Can someone here who did this job before for your stand, please tell me what is the best way to do it without damage to the stand ?
Thanks.
