@thecurse I replaced my DSi shell for a transparent blue and I still think it's the best looking portable console I own, right beside the metal red original 3DS.
@Lumeinshin @thecurse The one drawback of transparent case is that light goes through the shell and could potentially damage the inner electronics if left for too long exposed or at a high temperature.
But I'm a sucker for seeing the chips and motherboards of my devices. I blame the GBC cartridges for that.
