One time around 2012 I was buying a laptop for someone who needed a Windows machine. Knowing the poor build quality of various low end options we decided to splurge and get a top of the line Dell model with a nicer magnesium case etc. with a price tag close to $2k. We unboxed it, powered it on, and were greeted by a loud grating noise that went away if you flexed the case.

Returned it immediately been using Apple laptops ever since.
