what's the craziest deal you've gotten on PC parts? Where was it?

my pc’s slowly starting to slow down but I can wait a year or two. looking for some crazy deals i can start looking into soon

I took a shot on a Amazon open box motherboard on my most recent build. It was a pretty expensive board but saved $100. It was like it was opened looked at and shipped back. All the parts, stickers and everything was still in the box and a lot of stuff was still in the little separate baggies.
