So what do think would be the best method to SE a GPU?

If anyone has something that worked recently, I'd gift you a few steam games.

And on ebay germany there's quite a few big sellers like NBB, computerunivverse others, official asus store too, might be different elsewhere.
I just read on a previous thread that ebay usually sides with the  customer, but stuff like that changes all the time...

Ive been thinking about dpd dna too, since they have a bad reputation.

Bought a computer off amazon, took the GPU (4090) and replaced it with a low end GPU bought for 200$ on marketplace.

it's been a year and haven't heard about it.

Amazon are fucking lazy with returns... I have returned an harry potter lego castle (6000 pieces 500$ cad worth), I had it for 4 years and everyone I know builded it, many missing pieces, box  in very bad shape. So I bought another one on amazon and returned the old one lol. never heard about it.

There is much more opportunity to this SE thing than just claiming DNA or some other form of it.

I've done a few things like that, though returning a computer for 4k or more would def be checked by them normally.
I'd say that's luck.

Just swap the PCB, its easy.

Buy a low end GPU, which got 3 Fans
Take out the PCB, put it in the 4090 case.

Reseal everything, call it a day
