This unit arrived looking brand new. I did hear something rattling around inside when I removed it from packaging. I opened the unit (simple process) to find 3 screws with a blue rubber washer rolling around. I just took them out and place the lid back on before power up. This unit comes with a keyboard and mouse (new) but the quality is on the lower side. Don't get me wrong, the price point of the unit makes is a good value so I didn't expect a keyboard and mouse to come with it. The keyboard stopped working after 2 days but the mouse is fine. That's the only reason why I didn't give this review 5 stars. I do like the computer and plan to buy one for my son.
