The frame of my stand is black powder coated steel, although no overhang - just built to the footprint of the tank. It is skinned with detachable wood panels on the front and sides (built by a woodworker friend of mine):
There are adjustable feet on all four corners of the frame for leveling. The top edges of the panels are beveled a bit. The front panel is wide enough to overlap the edges of the side panels to hide them:
There are metal tabs welded onto the frame in the corners, with holes drilled into them. Knobs with bolts go through those holes and into threaded fittings on the backs of the side panels to hold them onto the stand, and make them easy to remove when needed:
A couple other useful things that you can't see from the pictures:
- There are small strips of wood that overlap the door openings from the inside by about a quarter inch, including a small strip that runs up the back of the left-hand door which overlaps the gap between the two doors - this keeps the fuge light from leaking out through any of the gaps.
- There is an acrylic drip pan with two-inch high walls that is the exact size of the inside of the frame, and sits on the bottom bars. All the equipment sits on that. It's really nice that it is watertight since I don't have to worry about small splashes or drips or leaks. I have a leak detector sitting in the pan in case of bigger leaks - if that happens the pan will hold a few gallons of water which will at least give me a little time to do something about it.
