If there was one point I was desperately attempting to make in this video, but feel like I kind of brushed right past it, is that by checking-in your components as soon as they arrive, making sure nothing is damaged, missing or mislabeled, you assure yourself of having time to get what you need before it becomes a crisis.
The byproduct of having done so is you make the assembly process go much faster since all your components are sorted per cabinet.
