Super clean, fully functional laptop.  Several upgrades (16GB RAM, IPS screen, 2.5" SSD).  The original TN screen was terrible, so I installed an IPS screen that fits and works perfect.  It ran Windows 10 Home at one time, but I used it most recently as a Linux (Mint) machine.  It's still very responsive with Linux!  Access to an optical drive is nice too as an emergency backup, should you need to use a CD/DVD in some way.

There is no OS currently (SSD wiped, ready for you to install an OS of your choice).
