Might be a lil hard to see the whole thing, but here's mine. There are two baffles, one 8" tall that is behind the wood and the other is 5" with plastic light diffuser cut to fit on the top to keep the chaeto in the middle.
Still waiting on my skimmer, but that first section will fit an Octo, Euro-Reef, ASM or whatever plus the heater.
People do overdo baffles, I get 0 micro bubbles in my tank (tested with a friends skimmer). All you need are the baffles to seperate your areas, not those three stagered ones you see alot of people using.
