I've built several stands using only 3/4" plywood.
The latest one shown here for a 125 gallon
Here is one I built holding a 180 gallon acrylic tank.
The thing is if you build it correctly you don't need a 2x4 frame. I believe most of the stands I've seen on RC are simply over built. Many will say its better over build than not to. Id take a well built plywood stand over anything built wit 2x4's it just gives you a much nicer interior cabinet space.
