This is Dell Optiplex 790 with 6GB of RAM and a quad core i5. This a great choice for students and office workers. Also great for a house PC. It is an ultra small form factor which means it is really small as compared to typical desktops. Check out my other computers that might better fit your needs, Gaming or otherwise. Here is a list of specs: Quad-core i5 2400S 6GBs of RAM 500GBs Hard drive Internet: Ethernet USB Disk drive Display output: VGA This does not have an OS. I will install and activate Windows 10 Pro when requested for an extra charge. Note: everything is working at point of purchase. I do not warranty the product after purchase and tested for working. This is sold as is. It is in a used working condition. It has a few scratches and dinks. If you have any questions or concerns please contact me and I’d be willing to help. Thanks.
