Hi I got Nvidia Galaxy Geforce GTX260. This one doesnt come with a backplate. So I ask if there is that I can buy. no one is certain and they advice making custom backplates. but how do I do it? well Ive seen some forums talking about what to use in making backplates (aluminum,acrylic, etc.) but i havent seen any forum talking about how to make it. They already now how to make but I think no post on how to do it. i could actually start making it if the issue is resources because I got no problem with any kinds of materials. But I dont want to destroy my gpu of course. I want to know what are the things to be considered to keep it safe.
