Hi Praszewski,
This build looks nice, but if you have an OEM Microsoft license, you won't be able to clone your Windows to the new SSD, because the operating system is connected to the motherboard of the computer on which it is installed and when you attempt to activate it, you will most likely not be able to (furthermore, it is even possible that you get the BSOD). That's why I would recommend you to do a fresh install of the OS.
Hope this helps
