If the other computer carries another motherboard, it's probable that Windows becomes non-genuine. That's a problem since when you try to activate Windows it will tell you that you can't since that code it's already been use by your other computer.
This is one thing I dont want to encounter since activating issues can cause other issues. These machines as far as I know are identical, since they where purchased at the same time and we purchased three of them at the same time.
But then again even if the same model they may have different components.
Thanks for your response.
