I recently stumbled upon a new source of shiny, high quality case feet: sign standoffs!
What really appeals to me about them is their diversity and availability, though I am a bit put-off by the price ($30-$40 for 1"x1", $8- $12 for 1/2"x1/2". However, that's about as expensive as other case feet (not including the little acrylic ones). Everyone likes seeing originality and variety in case mods, and these are an undisturbed gold mine of beauty and wonder. Quick, before someone else uses them first!
