I worked on the franchise from 1999-2005. My work was primarily CGI in the video game side of it, but I did help out some friends with some CGI projects for the shows and Nemesis. And I do know that the ship in the opening credits is a full CGI model, however only the aft section is shown. Looking at the pic again, it cant be the ship from the opening, as it features TMP warp nacelles, and the ship in the credits is round, pre-TOS nacelles. But it looks like that is the ship the guy was going for when he began cutting up the Miranda.
However, he could also have been going for the Harakawa Class. However this is more made from a Constitution class.
I'll see if anyof my old pals from back then have any more shots of it.
