Sorry if this is the wrong forum for this post.

I'm going to be re-purposing some cheap thin client type computers for some retro dos/windows emulation. And I was planning to repaint the cases in some interesting colors. I've heard that sometimes dyes are better for this than spray paints. Can someone suggest a brand of rattle can they like for this kind of thing? Something with bright non-transparent colors with as little build up as possible would be ideal. Thanks.
