<Edit> Ha ha, funny web app cutting me off in the middle of a post. </edit> Hi all, long time lurker, first time poster. I'm planning to purchase the refurbished dual 2ghz Power Mac currently listed on the Apple Store's "Special Deals" page, but can't determine if the model they're offering is a Revision A or B. The only difference, I believe, would be the inclusion of the 970fx in the B, which I'd like to make sure I get, if possible. If any of you know who I can contact at Apple to find out for sure, or if you see something in their listing that I'm not, please help. Thanks!
