One time I had some super cheap generic cpu cooler that said it was compatible with the b350 board I owned in particular so I purchased it. It wasn’t properly sized but because I got the board for $25 I said fuck it and I forced that thing on there.

The board bent like a bow being drawn, was insane. I took the cooler off, board bent back, I put some parts in to test it, and it still works to this day.

PCBs have some natural play, surprising amount too. But it’s the angle that matters. If you bend it too sharply or over too small an area, the copper traces inside the board can be damaged, or small resistors and other components can come unsoldered/detached at certain points. General rule is not to bend when possible, but if it does it will probably be fine unless you’re being really aggressive with it.
