I didn't know which category to put this in, but I just put components because this has to do with a case. Anyways, I have a prodigy M without a modular power supply, and instead of getting another power supply I'm just going to vinyl wrap some cardboard and add some 3D design on it. After that I'm going to put it in between the window and the power supply to make a custom PSU shroud, but I dont know how to put the cardboard vertically on the case without it falling, so I need some recommendations on how to make the cardboard stand I want it to be without making the mod look bad.
