One of the main consideration of acquiring a refurbished system is the reliability of the vendor. I purchased this product from this particular vendor because I saw 5 or 4 star reviews, and now I know why. I have read reviews elsewhere about customers getting products with spec not as advertised (different sizes of RAM, hard disk type, etc).My initial expectation (for a hardware spec for this price) is not really high, but the unit arrived just one day after I ordered it from Amazon. I immediately ran a System Information and noticed the second processor and 32 GB of RAM were not reported. I called the vendor immediately and they guided me through the troubleshooting. Note that last time I worked on a desktop computer was 20 years ago, so I wouldn't consider myself "handy" in that regard. It appeared that we had a riser (where the second processor and 4 additional sticks of RAM were located) faulty. The vendor immediately sent another riser (which arrived the following day) and it worked like a charm. It didn't stop me from working on the rest, such as slapping an SSD and installing the operating system (Ubuntu server).i only plan to use it as a Linux server, deploying microservices on Kubernetes, so I can't comment much on the sound or video cards if you plan to use it to play games. But even if you have to swap with better cards, the price of this system is still a steal. I have seen systems like this at least twice as expensive.Great system, great price, great vendor... I'm impressed!
