I bought this to replace my wife's aging desktop. I have a similar piece of equipment, also Dell, at work and it has never had a problem. Solid State Drive, so nothing spinning. ample USB and video connections (no VGA, however). Powered right up, smooth Windows 10 setup. I remember the days of 386's and a stack of floppies--setting up a new computer would take two of us a twelve-pack: "autoexec.bat, what does the soundcard say to add to that?" Bygone days! I was online in just a few minutes. There's no internal wifi, but it came with a USB wifi dongle in the keyboard box.There was a small rattle from inside the case when I unboxed it. I opened the case and there was a loose jumper switch inside. I checked a manual I found on the Dell site and could only identify one jumper on the motherboard and it was in place. I was encouraged to find the random jumper in there, as it indicated to me that someone had opened the case and gone through it. And indeed, it was clean inside and outside, totally refurbished. The hardest part of the setup was trying to install Office 2016 on the new box, as the license had already been used on the old PC. Tried again a day later and it worked.Very pleased with the purchase.
