I have my studio in what used to be a home theater room. The previous owner had a cabinet with a glass door for all the a/v equipment. I turned that into my photo gear storage/display and have everything but my lights which I leave up in there.
My day to day gear is in my bag which gets stored on a shelf in the display case. I really do need to organize the display case better for display and find a few small bins to put chargers and batteries, spare cords etc... in to make it look neater.
Something like this should work well for that.
Obviously, I don't think you'll need 4 though.
