Company I worked for was the only importer of Corsair chairs into Australia, we were told by Corsair (on a chair by chair basis) to have end users destroy faulty chairs if no replacement parts were available.

Same thing with Lian Li, we had a batch of white cases with a paint defect, they were never sold onto end-users but our warehouse teams destroyed every case, sent images to Lian Li of the destruction and we were sent another shipment.

Cooler-master had some bad mITX PSUs, same deal, sent the boys out with a hammer and safety squints.

At the end of the day it's cheaper for everyone involved to not have a faulty product that is too costly to repair shipped across the ocean or to a local disty. Sucks for the environment, sucks for the end user having to dispose of a faulty product but it makes for some interesting emails sent out to customers :D
