Great: Meaning this machine has very minimal wear, scratches, or dings. Some machines will even be in "like new" condition. You can still expect some small signs of usage.
Good: You are getting a reduction in price for a good working computer, with the expectation of one or more noticeable cosmetic defects, such as a small indention, a slightly bent corner, or a larger scratch.
All of our machines are in known working condition, have undergone diagnostic testing, and are in quality condition.
