25" chasis / 23" screen size 128 GB 2.5" SDD (6Gb/s with 8 MB cache) 8X Slimline DVD-ROM Intel Core i3-2120 processor @ 3.30 GHz 4 GB DDR3 Memory Windows 10 64 bit Wireless Mouse and Keyboard Brand new SSD installed; upgraded to Windows 10 64 bit. This is an All in One unit, the PC components are built in to the back of the monitor casing, so there is no external tower to install. Very easy setup, no cables (only the power cable and network cable) so set it down and power it on. Could use a wireless USB / WiFi adapter to bypass the network cable. Great for kids rooms, dorms, home office; anywhere. It does have a VGA output on the back, so you can connect a secondary external monitor to run dual monitors.  Unit is re-certified, great condition. Price is firm, must meet near Manchester; cash only, sale is final.
