I want to have my system with me in another city. I know that it strongly depends of my chipset. I have P35 (Gigabyte P35DS3R). Another machine also Intel-based but chipset is G31 (MSI G31TM-P35). Is it possible that my system will start on that machine when I plug in my hdd?

Windows 7 will be aware that the hardware has changed and will ask you to call an automated 1-800 number to verify and re-activate your Windows installation and again on your return when you plug your HDD back into your current system.

Always remember
Microsoft can and will limit your number of activations, eventually making it more and more difficult to re-activate. I wouldn't recommend switching on a regular basis.

@ChrisF - Thanks and good point... added to my answer – th3dude Apr 12 '10 at 14:03
And at any point, if they feel like it, they can say you're trying to activate too many copies with your key and refuse to let you activate it. – BBlake Apr 12 '10 at 15:24
Yes, this is also true. I was going to put that disclaimer in my original answer. I'll do that now. – th3dude Apr 12 '10 at 16:48
