I think you're allowed to change 1 major component at a time during your build for a certain period of time before the reactivation prompt is triggered. (e.g. one major component every 5 months will not trigger a reactivation prompt, but 3 - 4 changes in the same week would.)

From the website:-

Windows Product Activation checks eight different categories of hardware:
  • Display Adapter
  • SCSI Adapter
  • IDE Adapter
  • Network Adapter (including the MAC Address)
  • RAM Amount Range (e.g. 0-512 MB)
  • Processor Type and Serial Number
  • Hard Drive Device and Volume Serial Number
  • Optical Drive (e.g. CD-ROM)
Here's another site that explains what's it's all about (It was written for XP but i think it's a good read)

You can reinstall retail Windows 7 full version anywhere you want as often as you please as long as it's on only one machine at a time. So changing hardware isn't an issue. Even with a mobo change which triggers reactivation it is full retail so it is automatic.

What some interpret as rejection is actually the way MS Activation servers determine if you are moving it to new hardware if there are mobo or major hardware changes, by asking how many installations it is installed upon. You can only answer one, as this gives them authorization to deactivate it on any other than the new hardware signature which is then recorded for that Product Key.
