I bought a single tier fabric stand because the photos show it comes with a center support. It's pretty strong. I use it to support my computer and store laptops and the like under it. The length is only about 20 inches which fits my phanteks p500 pretty well. The only downside is that there are no instructions, but if you've built something from Ikea you can find out pretty easily. Also, make sure that if you plan to use the fabric side mount, attach it before installing all the screws. It sits between one of the side panels and the top, so you really have to latch it if you're going to use it. Too bad you can't just switch it or switch sides.
