I was in the same position - so happens that I had never used mine because I have been powering my Pi from a home made powered hub and a much beefier power supply ever since I got it.
After reading the explanatory letter (full marks to CPC for being so straightforward about what the problem was, and for sending me a replacement before I even needed it), I looked at the original PSU and sure enough, only the slightest bit of force was required to pull the back of the casing away from the front, exposing the PCB inside.
The fault was just as CPC said it was: The two case fixing screws were too short, and therefore only hanging onto a couple of millimetres of plastic which snapped off when subjected to only a little bit of force.
The letter said that if I sent the original PSU back, what I paid for it would be refunded even though they had sent me a replacement supply. - a good way to try to ensure that the faulty ones are removed from circulation, I thought.
I'm not actually going to send mine back - I found some better screws (same width/much longer) and fixed it, because I had another Pi on the way and needed a PSU for it anyway. If the cover is securely fixed - with decent screws or decent screws AND glue, (but definitely not just with glue) then in my opinion as a hardware technician, these PSUs do not present any threat. If I send it back, then a perfectly decent bit of electronics will end up in a WEEE bin or in landfill.
