New Build & Drives

Hello folks, not been here for a while due to medical stuff, am fine now as evidenced by the following burst of activity:


I attach details of a new build that I am currently working on. I have backed-up my original system to my NAS and to a 32GB USB key. I would be grateful for advice.
I have a Full Retail, genuine copy of Windows 7/64 bit to transfer from donor to new build. I have transferred contents of 'E' drive to 'C' drive, then cloned 'C' to 'E', using Macrium, which I recommend for its simplicity and ease of use.
I intend to install clone 'E' to the new build, leaving the SSD Ready Cache, and 1 TB. Hard drive, unplugged, to be plugged in and setup later, to avoid any drive letter problems.
Can I install 'E' to new system (which will become 'C' in the new build) and expect Windows 7 to work in the new system, without problems? I have my COA from the original retail disc and will format the 'C' drive remaining in the old system, thus removing Windows from that machine. I understand the fact that the new system is quite different hardware to the old, but don't know if this will affect Activation.
I am aware that the Hdd spinners are SATA2, these are from my old system and may be replaced at a later date.
Many thanks for any assistance.

Bertison, I don't think you will have any activation problem. If you do just use the phone method

Activate Windows 7 by Phone

I would just like to add, for anyone using the same mobo/Alpenföhn CPU cooler combination, that there is a problem. The RAM lower socket (nearest to CPU) cannot be used with this cooler, because the fins project slightly to prevent it being fitted. No problem for me, I have enough memory at (2x4 GB) in the other two sockets. Note that this is not a Height factor of the RAM, but a Width factor.
