Agreed. But sometimes it's the people who install them. We recently had to move data centers in the middle of our current film production. We did most of it in small windows over the course of a month, leaving our Isilon cluster for the final push on a Saturday. To make this possible, we pre-loaded the target racks with new rails and cabling. The first two racks went smoothly. The third rack went smoothly right up until I put the second to last node in. It was only then that I realized that the ding-bat who put the rails in the racks had put everything in this last rack off by 1U, leaving me with 1U for a 2U box. After much cursing (much of it at myself for not catching it beforehand), we spent the next two hours yanking it all out, unscrewing all the rails, and putting it all back together correctly. This was a containerized data center too, so only room for two people to perform the work. Good times. The upshot was that we turned the cluster on, and aside from replacing a bad SFP, it worked without any reconfiguration.
