I'm thinking of building my own PC but unfortunately, I'm living in a very humid area. I'm afraid that parts of it might corrode or something? Especially the casing/body. I do want it to be somewhat metallic though, so if it's possible, please don't suggest plastic. I have found a couple of stainless steel options, but I'm afraid they might corrode after a while, especially when there are tiny scratches and stuff. Has anyone ever hardened steel by themselves? I've been thinking of buying one of these boronzing agents and doing it myself. Has anyone ever done that?
