Kadath,
Microsoft has a utility for Win2K and XP called sysprep. It is on your installation CD. Sysprep is a system preparation tool that is designed to make rollouts of machines easier for companies.
Here is a link to the Microsoft website regarding sysprep with Win2K.
You can sysprep your hard drive, toss it in the new system and then boot up. It should pop up and go through the hardware detection process. You can install any drivers for stuff Win2K doesn't recognize. You will also need to reenter your serial number.
I use sysprep with WinXP all the time for rolling out new systems at the office. I have used it to create a win2K image that has been rolled out once or twice as well. As usual, make a backup of all your important stuff first.
