Edit: yes these are "Scatch or Dent Grade1" but you'll be hard pushed to see any cosmetic damage. Dell for some crazy reason label this as "considerable cosmetic blemishes" well i've had quite a few laptops from the outlet and there has barely been more than a hairline scratch on the glossy lid that you have to hold up to the light to see.
