21st Century Decluttering sent in a ClosetMaid hack/mod - "Sometimes you just need to convert your clutter. I had several long pieces of ClosetMaid shelving the garage. They are easily found at garage sales when people remodel. Even new, these pieces are surprisingly inexpensive, as I believe that ClosetMaid is doing a 'razor' and 'razor blade' strategy by selling the shelf part cheaply and the posts and shelf holders at a premium price. They are ridiculously strong and fairly light. By bending them appropriately, you can convert these shelves into a variety of useful items: magazine holder, monitor stand, paper tray, etc. " - Link.
