This is the only desk I could find that suited me. The metal poles have two extra holes to adjust the placement of the shelves. I have one shelf attached at the bottom and the other at the top. My PC tower fits beautifully on the bottom shelf several inches above the floor. A few holes didn't line up exactly, but my son was able to put in the screws on a slight angle. The desk is very sturdy with simple lines. The price was very reasonable too!
