The unit arrived this morning. Well packaged (foamed in place in the box) and shipped quickly. This unit came from Stallion Tek. The exterior was clean with some minor scratches, but overall fit the description as a refurb. Popped the side panel off and checked under the hood. It has four 4 gb RAM modules instead of the two 8's that some have received. I noted another reviewer had a problem with a wire that had gotten jammed  into the cooling fan blade that woofed the power supply. In this case there were two wires (looked like supply power to the SSD) right against the fan housing so I took up some slack in the wiring and eased them back from the fan. Other than that little adjustment it looked fine.The unit came with a Displayport to VGA adaptor. I wanted HDMI and had ordered the adaptor so no big deal. It came with a power cord, keyboard, and wifi dongle, but no mouse. No big deal as I wasn't going to use them anyway. It also didn't come with the Windows 10 disc, something that was part of the package (I'll follow up with Stallion Tek). Installed a Logitech wireless keyboard dongle into a usb port and started it up. It booted right up and setup was pretty simple.This is a quick machine! It has a little help as this one shipped with an I7 4790 processor (bonus)!I'm thoroughly happy with the unit straight out of the box. I own a few refurbed Optiplex pc's for our business, and for the price you can't beat them. They aren't sexy but they are well built and last forever. I'm hoping to have the same experience with this one.
