Can stickers inside your PC effect anything?

[reaper211]

I thought it'd look cool if I sticker bombed the inside of my pc at the bottom where it covers the psu and storage. Do stickers have anything about them that would effect something being inside the case?

update: Stickers would be average material, just glossy.

no impact as long as you are not covering the ventilation holes

Assuming the stickers do not become unstuck and get sucked into fans and blocking vents, it is probably harmless. And it is probably not advised to put stickers on the metal heat sinks either, because you would be reducing their cooling efficiency even if it is not by a whole lot.
