I noticed a lot of listings for CPUs and GPUs on ebay that clearly state not working for parts only.
Why bid and pay for something that will not work? Some are asking/bidding a good deal of money.
I can see maybe a GPU where you just need the cooling solution/fans, but other wise why?
Some do say as is not "working," then go on to say "It was working when I took it out, but buy it as not working I take no returns"

My take on it, they want to be able to tell eBay the item was clearly dead and not working if they have someone try to screw them over and get a refund.

Or Ripe Off the OEM under an RMA

I don't think doing a RMA is a ripoff. If it is under warranty then it should be replaced.
They cover 2nd and 3rd hand hardware, if it is broke they should fix it, or don't warranty it.

Cool, I did not look at it this way.

I personally don’t have an issue with it, as it is warrantied for a reason, but I don’t agree with trying to hide a defect (maliciousness) to replace a broken product.
