There is no way to determine the use time of the hardware on the computer except the hard disk. Whether it is a refurbished machine can only be determined by observing whether the screws have been removed, whether the body has been removed, and whether there is dust at the heat sink. This requires considerable experience and subjectivity.
It's hard to say, because the production date of the motherboard is before the date of your purchase, and you can't determine how early it is, maybe a month, maybe half a year~~~
Have you ever eaten a cake?Do you think eggs and flour will be produced on the same date as cakes? The computer is to be installed. If it is installed today, the factory date will be today.As for the motherboard, of course, it was produced before today.
