3/4" is plenty to hold that tank...
80# is not that much weight, think about it, I bet you have set down on more flimsy furniture than that.
Most tank stands I have seen are WAY over built.
I would suggest making this whole cabinet out of 3/4 " plywood, and covering the entire back of it with 1/4 inch plywood. the back (1/4 inch plywood) will keep the whole cabinet square, and wont let it fold over like an accordian.
get your 3/4 plywood and rip it to the depth of your cabinet (IDK 14-16"?)
If you keep it under 16" you can rip a sheet of plywood into 3 equal strips, about 15 1/2" each. Anyway.. rip the plywood into 3 strips...
Build the box that makes the 2 sides, and the top and the bottom...
Make sure it is square, and nail, and glue the back on...
then cut the center vertical divider. glue, and screw in place..It will provide the lateral support for the top.
then cut the shelves, you can mount them with small blocks or brackets, or even dowel pins..
Always use yellow wood glue.
Always try to use screws.
If you use screws always drill the correct size pilot holes.
When the cabinet is finished, you can face out the front with some 1x2's or use some wood trim. they make outside corner trim that covers the plywood edges very nicely..
Whew! I am tired now, Think I got carple tunnel or something...
and I need a beer...
