I'm thinking most companies would say not to open their products and they would rather fix it themselves. Seals, void stickers in the USA at least are not enforceable. The PC runs one program, doesn't work the PSU at all. I'm not worried about if the CFM is perfectly the same. 
 
They put labels on stuff, like "don't eat soap" or "don't eat tide-pods", because, for lack of a better word, stupid people have done it. WIth a background in electronics, I know not to touch compounds in a PSU, even after it has been unplugged. 

Fairly certain that if someone died or got injured from a shock from a power supply...the manufacturer of the power supply would not be able to be sued. There are warnings present on the power supply itself, and in my opinion, because electricity has the potential to be so dangerous, the individual should be expected to educate themselves on such issues before attempting repairs. In other words, whatever injuries they experience due to electricity directly that _isn't_ a design flaw with the product is their own fault. People need to take responsibility for their own actions, and in this case, the manufacturer would NOT be responsible, even remotely.
 
Additionally, voiding a warranty due to someone tampering with a warranty void sticker is NOT legally enforceable, at least here in the states. And in my opinion, if a product has issues after a repair, a manufacturer must be able to prove the modification itself caused the fault...Just like with a car.

That's actually illegal in USA    call them on it.
