I bought a 30" Brooklyn stand from Petco... not bad for $50.00
However once I really started getting things going on my saltwater tank I noticed that there was a bunch of "stuff" accumulating under the stand so i headed to Lowes and spend less than $30 on wood.. even had them cut it!
Side pieces are compression fit and the front door has 2 hinges, a handle and a magnetic catch.
I also grabbed a few pre cut piece of Conduit and bent it to hold the lighting fixture. That is secured with clamps.
Here is the finished product.
