Note: if the ad is up, it's still available. I just finished upgrading and refurbishing this unit. I added RAM and replaced the old hard disk with an SSD. It performs great! It was too slow for Windows, so I installed Linux Mint. It runs really fast and is super easy to use. Software includes Google Chrome, Libre Office, and much more. Specs: AMD E1-2500 dual core CPU 16 gb RAM 250 gb solid state drive DVD/CD RW optical drive Includes built-in WiFi and keyboard and mouse.
