The Monogram Enterprise is a reissue of the 1960s Aurora kit, whose molds Monogram acquired when Aurora went belly up, The kit was impressive for its size in the day, but is not generally too well regarded as a scale model these days. I believe it was last reissued around 2007 by Revell, now owners of Monogram and Aurora by default.

If you search the webs, you'll find a fair number of builds of this kit, and comments on its inadequacies.
