PCI Slot Covers

So I'm still in progress of building my first PC. I have the case (CM Elite 430) and are now reviewing the PCI expansion slot covers of all things. They're not screw and un-screw covers but rather soldered to the adjacent metal and are rather flimsy. I would like to replace all the covers with some metal mesh covers instead.

They say they are in the description, but are all extra PCI slot covers truley universal fitting in terms of size? Having never changed the covers before, looking at them I'm actually unsure of how you would even fit them in since there would be no hole to screw them in place?

 

yes, they are all universall, you should be fine
