If the listing didn't explicitly state this was a preowned device, I would have had no clue. Inside and out this thing looks like it came off the assembly line yesterday.Taking the machine apart to add a secondary M.2 SSD hard drive was easy. After which I reloaded the OS on and ran a Winaero WEI benchmark test(the attached screenshot is the results of the test)This is a great little machine that is well worth the money
