@ mrbee I think it was a metal stand with wood panels. I am planning a wood frame stand and was going to put metal strips on the leg supports to catch the magnets on the doors/panels.
@chris I was debating to go with a thick plywood that wouldn't need to be braced, but I think that would be too heavy so was thinking something lighter and brace it on the back like you talked about. I like the lip on the bottom to help replace the panels easily. SO you are using a magnet on both side, kind of like a magfloat to hold the panel in place? I like the lip at the top to open. I was thinking about some really nice clean hardware handles. They are not cheap though. I was going to have 3 seperate panels on the front and one side panel, so 8 handles.
@kspops I am going to oversize a little, but the tank the stand will hold will be 60x24x24.
Are you all glad you went with magnets?
