Once Windows is installed run Windows Update repeatedly to install all drivers and necessary updates, if you have to reboot run Windows Update again on rebooting. The installer will format the drive, create the appropriate partition structure and install Windows. Then boot the Windows installation media, select a custom install, delete all partitions on your SSD (so that the whole drive shows as unallocated space) and then click the Next button. When your new PC arrives and you've set it up, move your existing SSD across and install it. You'll then have a copy of everything you have installed now. On your existing PC install Macrium Reflect (free) and take a full image of your Windows partition to an external drive. Here's how to preserve as much as you can. Your existing MBR formatted SSD will not work at all in a UEFI/GPT system. Your new PC will use UEFI and the drives will need to be GPT formatted. And not only for the reasons above.your existing PC is most likely using legacy booting and not UEFI and the drives will be MBR formatted. You cannot just plug your existing SSD into the new PC and expect it to work, it won't.
