Angels have the Phone Box
I don't know about the previous key/activation. If you had an eligible W7 or W8 key, that should have sufficed for MS.
That OEM edition is fine, (and probably cheaper at Newegg), EXCEPT, it is not a retail key and therefore not transferable. Might be worth the extra $, if you plan on moving it to another system in the future. OEM System Builder, like OEM pre-installed OSs, are tied to the first system they are activated on, and can not be activated on another system down the line. For transfer-ability, you want a full Retail key.
