We bought these with the idea that they would be the base for a desk. We had the top already, and the intent was to put these cabinets on legs instead of castors with a table top anchored to the top. We quickly realized there is no way to take the drawers out to anchor the top to the cabinet. Also, the bottom of the cabinet is open , so there isn't really a way to put legs on it, either. As for the castors, if you put them on using the hardware provided, they don't stay on if you move the cabinets around much. The metal of the cabinets is kind of flimsy, so a lot of use for these is probably not a good idea.
