Ordered this to use as a dedicated media server. well packaged and looked like new except for the scratch on top from a monitor everyone seems to have. I noticed something rattling around inside the case so I popped it open to blow it out and noticed the mounting screws for the dvd drive were not installed and sitting on the MOBO.  make sure you check it out inside before powering up or you may let the magic smoke out.The inside was impeccably clean, shiny even, it literally looked brand new. RAM is 2x4g and 2 open slots. DVD is read only no burner so I swapped that out, added a 2nd drive which requires a SATA cable, however the power cable is right there under the DVD drive.I added a USB wifi dongle and went through the Win 10 setup, it did not ask for the license key (which is a refurb bulk key on the side sticker) and went through the usual steps before it updated. whole process took about 30 minutes.the machine is fast, quiet, clean, and does everything it should. the large amount of USB ports (especially the multiple 3.0) are a definite plus for adding external drives for a media server.since the DVD drive was not a burner, I could only test the DVD rip speed, which was only slightly faster than my duo core G3240, however, the processor used only half the power when transcoding videos to two users while ripping a DVD and sending files across the network--all at the same time--which usually caused my older Dell to slow to a crawl.very pleased with this setup and it is much better than most of the new home systems from the box stores at 1/4th the price!
