It\'s been used a lot but when it was passed down to me, it all worked. I just didn\'t have the right connection to display it. It comes with everything seen in the picture. It should be exchangeable/upgradeable it just doesn\'t come with a harddrive. It takes a 2.5\" SATA HDD. Personally I would recommend getting a Barracuda hard drive. I will include a power cable cause you kind of need it. I don\'t know the specs or anything of that nature. It\'s been too long and I never wrote it down.
