Needing ideas for stand and canopy

[Toxik]

I'm looking for pictures of some stand/canopy combinations that have been built using a 2x4 or 4x4 frame. I'm having one built and am having a hard time convincing the guy (cabinet maker) to make a frame under the plywood. He thinks it will be strong enough (and he might be right), but I would feel a lot more comfortable knowing there is a strong frame that won't distort from the humidity. The tank I am upgrading to is a 90 gal that has 2 overflows in the back (not bottom).
I'm also looking for ideas on design and a "user friendly stand". The ideas I have so far are quite limited.
The stand will house a DIY acrylic sump w/ refugium, pump, in sump skimmer, phosban reactor, 2 ballasts for the lights, timers and plumbing. The lights are "Aquaperfekt photon plus" https://wwws.aquaterrashop.de/meerwa...oducts_id/5546 (this was a deal I couldn't pass up).
Any help would be greatly appreciated.
