The machine arrived well packed in mint condition. It really appeared like it had never been used. Did open the case to check things out and clean throughout. She's been in operation since January, 2021 which is going on 3 years and has performed flawlessly. One thing I do is do a complete fresh install of Windows and do not load up the manufacturers programs. This seems to keep the machines I set up happier, and everything in the Windows OS gets updated through the OS. The configuration is 16GB RAM with a 1 TB SSD and 3TB HDD which has been more than ample disk space, and she powers up very quickly, ready to get to work.I loved this machine so much that I purchased a P510 as a backup PC, but decided to outfit her for music production and just now getting it set up as well. Would not hesitate recommending either of these fine machines, they are an excellent value.The attention given by tech support in the refurbs has really been great. All quality components that will last for years. Definitely 5 stars all the way around.
