Comes with an SSD and Windows 10 Pro installed -- what else more can you ask at this price point. These units are an excellent cost-effective way to provide multiple workstations at the office or even if you just one a simple home office workstation to do some word processing, emails, or browsing. I'm sure you could do some light modern gaming with it as well if you upgrade to a decent low-profile graphics card for $50-$100.The bad: Needed to upgrade the GPU to provide dual HDMI ports and add some RAM. The chassis was bent in the rear panel and it was a struggle to remove the cover. Took a good 30 minutes of elbow grease, pliers, and a screwdriver to force the cover off. If you are thinking of needing to upgrade any hardware, beware of this issue.
