Question Scratches on the backplate of the graphics card ?

[furkansg1r]

Hello friends, last month I bought a second-hand MSI Gaming Z Trio RTX 3080. When I bought it, I noticed some scratches on the backplate, but I didn't ask the seller how they occurred, thinking it wouldn't be a big issue. Now, however, these scratches are bothering me a lot. Do you have any suggestions on how I can remove or reduce these scratches on the backplate?

This is where you should've asked where they came from. They are cosmetic, IMHO, unless you can take the backplate off to inspect the PCB underneath for anything that might resemble a spill from an AIO, namely the coolant leaked onto those marked areas.

Just another tip, take a clearer picture of the backplate, after setting the phone on a stand to negate the blur introduced from your hand(s) shaking.

They look purely cosmetic. Possibly a Sharpie to cover up the blemishes.

Or nail polish.
