I bought 3 for business purposes. 2 are great. 1 makes a loud whirring sound when it is running. Came with generic keyboard, mouse and Wi-Fi adapter. On all 3 the sound took work to get the headphone jacks to play sound out of the speakers but a little reinstallation of the drives and everything is okay now. All had Windows 10 and the OS works fine. They aren't made for gaming so if that is what you want, these are not going to cut it. I wouldn't purchase them for personal use but they work for business.
