Super disappointing, the holes lined up with about half of the time. The holes ranged from a few mm to a couple inches depending on the piece. Metal was scratched in some areas too. I purchased 2 of these and the variation difference was shocking. The metal brackets for the slide out key board are not heavy duty, flimsy, and even railings broke when trying to lock it.  So disappointing and not can’t even use. Over all spend the money on a higher quality desk. These are not worth it.
