I have never used washers before in a build but with my new case that's coming in the mail tomorrow (Fractal Design Define XL R2) people have problems mountings pci cards because some of them ship with standoffs that are too short.
Now, so I don't have that problem I bought some zinc coated steel washers, are these what I want or do I want cardboard? Some people say boards these days ground to the case (that's what I thought) some people say you still need to insulate your board from the standoffs. So metal or paper washers, what do you need to use?
