Good eye! I actually took apart my ED209 model (low poly one I used for Mechwarrior 4) to make that front end... *LOL* That was one of "based on" models, another was the heavy support fighter, loosely based on a Star Wars B-Wing.
The one I figured most people might pick out was the Planet Killer, which I made by heavily modifying a Krenim Time Ship (Star Trek Voyager) model I made years ago.
Although, out of all the ships I've posted I think I have to change my vote to the following...
I didn't make this model, simply because I'm great at modeling but suck at texturing. I did, however, make the modifications and simple lighting to it for a Star Trek RPG I used to play. It was capable of going 1 on 1 with a Galaxy Class.... *LOL*
Here's a couple shots after I added some more advanced lighting, effects & a basic starfield.
I think it looks better from the back angle, can't put my finger on what's wrong with the front lighting.
