It has dents on the back but when I put all together (20" dell monitor and HP keyboard and mouse), it works fine. Windows 10 & wi-fi setup went smoothly. The only thing that's not working is the CD drive. It won't open. However, that's fine. I rarely use it anyway. I can live with that. Primary use of this is for work. Internet connection via wi-fi works perfectly.Overall, it's not perfect (that's why I gave 4 stars) but I'm satisfied with it especially for its value of 160 US dollars plus tax.
