All components are built-in behind the monitor, so no big tower. Everything fits on a desk. Only ONE wire for the power! Intel i3 Model ZX 6961. 1 TB Hard Drive Windows 10 Home fully installed and activated (Genuine). All the latest updates! 8 GB RAM DVD ROM USB, HDMI, VGA Ports Wireless Keyboard and Wireless Mouse included. Wireless LAN System Rescue Disks, restore computer to its original factory configuration. Very good condition but.....no display on the touchscreen monitor. If you have a second monitor, it can be plugged in the computer and you get the display. Just put it in front of the unit and you are all set ! OR you can plug it into your TV and have access to the computer with the wireless kb and mouse. Works very good. The display on the computer could be an easy fix but I do not know anything about fixing computers. I can give you a demo before buying to show you how well it performs. Screen pictures were taken with a cheap camera. The screen display looks a lot better and very clear. Very good deal. Very good system.
