Based on some other, uninformed reviews (if I was also so uninformed), I might not have bought this. So a couple of points: Displayport is functionally equivalent to HDMI, and with an adapter, sends happy video out to HDMI monitors. My PC arrived with an HDMI-to-DP adapter, so I didn't have to procure one. Windows 10 was "real", all the USB ports worked, even the WIFI dongle was acceptable. No scratches or dents, I was up and running in an hour.People should have some idea what they are buying. These Optiplex systems are ubiquitous in corporate America. They are not gamer PCs. They are solid workhorses sitting in cubicles, waiting for that spreadsheet calc. With a few add-ons, you can make them into anything you want. I think the refurbs are pretty good deals, considering the cost overhead of a brand-new system.My new one (512G, 32G RAM, Core7 4-core) is used as a media center, to run a 65 inch TV showing movies and Hulu/Prime. Has iTunes, bittorrent, .along with some application development (VS), it handles all with nary a blip. 8TB from a Buffalo rounds out the config. Almost bought the bigger one with extra drive bays, but this is compact and can hide away nicely. A good deal.
