Your comment was made as if the DSR had been revised or removed, I'm well aware that it hasn't been changed or removed by the way.
The whole point in DSR is to be able to inspect items that you want to buy.
To abuse the system is to buy something with the intention of returning it as soon as you can.
Anything else is pretty much fair. If I bought something, and I wasn't happy with it I'd send it back, it's my money and I'd have worked hard for it.
With regards to that, I also wouldn't actually be bothered if I bought an item that had been opened, it comes with at least a 12 month warranty, if the item doesn't work as described, I have my warranty to back me up.
If the item had been tampered with in anyway, I'd return it for a replacement and I'd mark it somewhere (plastic) with UV ink to make sure they don't try to blag the same one back to me.
Tampered with to me would be the HSF being taken off for example, or there appearing to be dodgy solder points on the card.
Anything else, I'd have no issue with it, I'm buying the product regardless, it would have been handled by a load of people before hand in the factories and testing departments too.
When you buy second hand, the reduction in the price, more often than not, is due to the lack of a warranty, most people expect this when buying second hand, so no this is nothing like buying second hand.
If I have an issue and it's a geniune issue, I can send it back for a replacement easily enough.
In the case of overclockers, I could take it back personally to avoid costs as I spend a fair amount of time around the Stoke/Crewe area (OcUK store is just off the A500 which is the dual carriage way between Stoke and Crewe)
