What could this magnet be from (found inside computer)?

I'm not sure the proper forum for asking about unexplained magnets in computers. Feel free to move.

My TV computer failed with a BIOS fan error message. I opened it up and nothing seemed wrong, but I ordered a new fan. Yesterday when I replaced the fan, I found this square magnet inside the case attached to the VGA port. I've had this computer for about 9 years and only opened the case these two times. I do not recognize the magnet. The magnet is about 1/4 inch square and about 1/16 inch thick. It has either CY or GY marked in a side. Any ideas of the magnet source?

Since I opened the computer twice, I don't know if it came from the computer or if I dropped it in somehow from somewhere. The computer now works fine.

Was there a magnetic latch on the case?

Leave it alone. That is the only thing keeping your computer together!

That's a 5G NSA transmitter.

Not that I know of. There were four screws for four plastic posts that had some kind of latch (one screw/post in each corner). But I will check around tonight to see if I can see any latch.

I think the thick layer of sticky dust is doing a good job keeping it together!
