Low quality design. There are many, many screws and no easy way to rearrange this. In one portion there are two 6-screw metal plates used to hold two of the desk panels together. One of the cross bars has multiple L shaped brackets to avoid collisions with other screw holes. Many screw holes are right above metal cross beams that are very difficult to access. Compared to other flat pack furniture this one is more of a put it together once and forget it type furniture. For the money, I am thinking an l-shaped ikea desk would have been a better choice. I bought this one for some flexibility in shape, but it quickly turned out that rearranging it would take a very long time, in addition, I was considering adding a keyboard tray due to the height of the desk, but the metal cross beams make this very difficult.
