In my searches I have come across two different Xboxes at pawnshops but when I ask to see them to check the manufacture date I see that they have been opened. For $90 would you take the chance? Since they had been opened, I assumed that the previous owner tried modding it because what's the point of opening it up for any other reason. If it boots up to the microsoft dash the worst I can think of is that the screw had been stripped. Would you purchase the open Xbox or keep looking for ones that were not? I suppose if there is good indication that the DVD-Rom drive is a Samsung then I would buy it.
