It's nice to hear that this matter was attended to in a timely manner.
What people have to understand about quality control, is not every piece of equipement is inspected. It's a nightmare to even suggest this.
Systems are built on assembly lines, and one person installs drives, and another installs a power supply. It is entirely possible that the system was damamged 4 people down the line.
Now, think about the reprocussions of going to your supervisor, or lead person, and explaining to them that you just broke a computer, and it has to be sent back to a different station to be repaired.
So, you take your chances and hope QC doesn't inspect this particular computer.
No thought is given to the end result, because said person has manufacturing quotas to keep, and money to make. Said person probably doesn't even know what the finished product is supposed to look like. And, I'll garentee they don't care.
Now, why are manufacturing jobs going elseware???
