Reinstalling Orginal (Gray) System Discs with new HD

Howdy folks,

I've been considering upgrading my Mac Mini's Hard drive to something bigger even though I'm nervous about cracking open and working in such a little case I just might do it.

I have one question, the original discs that came with my Mini are the gray ones, I know they're locked down to specific machines. Will they install if there's a different hard drive in the machine?

At the rate I'm going I may just wait until I buy Snow Leopard to upgrade the HD depending on whether or not the $29 upgrade is going to be a full installer or just an upgrade version from Leopard.

You should be fine. It's the chipset that ties the disc to the original machine, not the hard drive.

I figured it wouldn't be tied to HD but was wondering about a hardware hash of some sorts. Thanks, CWA.
