Seen this a couple of times, with variations. :)
For high-cost items that can be stripped down, place a clear warning within the package such as:
Any attempt to disassemble the product invalidates both the warranty and any return. In the event of ANY problem, phone us on this number: 12345678. Removing parts will render the item NON-RETURNABLE and we WILL NOT refund or replace the item.
That should cover your A.
