This machine ran fine right out of the box.  It booted up, did a final Windows 10 installation, and just plain worked.It has a few cosmetic issues on the front, but nothing you even notice right away.  It comes with a wonderful Multi-I/O module that supports SD, MMC, MS, XD, and CF devices, along with four front-facing USB ports (2 each USB 3 and USB 2), and a DVD burner.  I should note that all of these devices are genuine Dell parts.The rear panel has even more USB ports (again 2 each USB 2 and 3, plus 2 more USB 2), two Displayport ports and VGA, and a built-in NIC as well.  It even has PS2 keyboard and mouse ports!The unit shipped with a generic keyboard/mouse combo and a tiny USB dongle for both Bluetooth and WiFi.I opened the case because I plan to add another hard drive, and I discovered the provided 1TB SSD was secured to an unlikely location with a single screw.  This is functionally fine, but I feel that SSDs need more heatsink contact than provided by a single (not really that tight) screw.The interior and some parts of the front panel were dusty, even cables that had to have been manipulated to work on the machine.  Again, not a problem at all, just dusty.The RAM, all 32GB (all this machine can handle) is from quality vendors, and 3 of the 4 sticks are identical.  If I were trying to push the envelope with this machine, there's a very slight chance that this might make a difference.  But probably not.Before I put the cover back on I noticed - and once again, this is NOT a functional problem - when I had the case open I noticed that the front of the case was bent.  Someone in the past really didn't like this case!  You can see the bend in the last picture, just in front of the hard drive bays.  But since the front panel fits well and the bend doesn't prevent drives from fitting in the bays, this is ONLY cosmetic.One final thing: there was no Certificate of Authenticity for the Windows installation.  The Amazon Renewed Store text on the product page says it should have one, but I can't find it, and I don't think the little "Pro Windows" sticker on the back counts.  It was a simple matter to get Windows to give me the product key, and Microsoft hasn't said it's not a legitimate copy, but it would have been nice to have some sort of "you're legal" documentation.Overall, this is a really good machine.  It came with great features, and except for RAM and the SSD all of the parts are Genuine Dell.  If it had been cleaner, had a COA (that I could find), and if the SSD had been better secured, it would have definitely earned 5 stars.  I gave it 4 because there's no "4 1/2" option.
