Black Beard - take a look at my "Avor" build. I wouldn't necessarily recommend that you (or anyone else) tries to copy it, but you might get a feel for the kinds of things that go into a machine like this. For example, those stepper drivers will very significantly limit performance.

As suggested, ask more questions before buying too much more, but welded steel box, Hiwin-style rails and ballscrews can give a very capable machine - I've recently been profile cutting small steel components with mine. Good luck with the build!
