Purchased this computer late July, it arrived promptly and in good condition.The computer ran and performed like a new machine out of the box. Corded mouse, keyboard and wifi-usb included.  I could not get the wifi - USB to work.  I contacted Cnbcomputers and they provided suggestions and a replacement wifi usb device.  I operated using an ethernet cord in the meantime.The replacement wifi device worked perfectly, I was wireless and running in minutes.A thought about communications.  My warrantee was through Cnbcomputers even though I purchased through Amazon. In this case, it is easy to assume Cnbcomputers has all the Amazon information.  It might be best if the customer overcommunicates early if questions or problems arise.
