Hello everyone.

I built my new computer a few weeks ago and have only one HDD which my OS (Windows 7 Ultimate 64bit) and everything else is installed on. Sometime before the end of the year, I wanted to buy one or two SSDs and install my OS onto one of those. I want to do a clean install but I was wondering.. do I have to buy a whole new Windows 7 Ultimate OEM disk for the key? Or can I just use the one I bought when I first built my computer? Thanks for the help in advance.
