PROS:The unit itself arrived on time in good shape with excellent packaging. Its clean, if it wasn’t sold to me as a refurb I wouldn’t know it was a refurb. The fan is quiet, I only hear it late at night (midnight) when there is no car traffic outside and the TV is off.I can compile programs in Microsoft Visual Studio 2019 in the background, have 5 tabs upon on Google Chrome browser and play Pandora radio all at the same time with no lag. Memory usage with all that going on is 6.7GB.The people at TekRefurbs, are some of the nicest people out there and will genuinely work with you to resolve  issues.  I had a problem and they did fix it, within two days!CONS:1) Originally, I did not get what the shopping cart description says.I received a DVD-R drive not a DVD-RW drive. Since flash drives are so cheap these days, I just back up my PC to them, I can't remember the last time I actually burned  DVD. And unlike a DVD, I cant really scratch a flash drive.I called TekRefurbs just to let them know, and they promised to send me the correct drive, even though I will probably never use it for burning any data. The new DVD-RW drive arrived today! Two day shipping via FedEx. Impressive! Especially considering I wasn't really unhappy. So this "con" was fixed.2) Some of the serial ports are so close together that one device I have plugged in is fat and blocks one of the other ports. But that's a DELL design issue. Luckily, there looks to be about 10 ports so no biggie, enough for my printer, two flash drives, wireless keyboard and wireless mouse.3) The provided mouse is the worst I've ever attempted to use. If you buy this PC and don't already have a mouse from an old PC then do yourself a favor and include new wireless mouse in your order. The provided mouse includes  random click sometimes and doesn't want to select text properly.When it comes to refurbs, I think you really have to pay attention to the vendor you are buying from. I always look at the vendors Amazon storefront.  If they have a 10% negative rating at any time in the past year, I pass on that vendor! And I only buy from Microsoft Authorized refurbishers. I"ve never gotten a lemon following those two rules.Overall, for the price I paid, I really cant do better. Customer service shined again since TekRefurbs also provided guidance on a video card upgrade that would fit (SFF) and not require a new power supply. "Gigabyte GeForce GT 1030 GV-N1030D5-2GL Low Profile 2G Computer Graphics Card". But now after running the Windows 10 "Display Color Calibration" tool and running Windows Cleartype tool, I don't need a video card. The text is much sharper and I'm not a gamer.
