It sounds like it came with a bunch of decent parts. Panasonic servos should be nice. Some Chinese motors are little better than scrap, others are fine.
The thing that would concern me the most would be the weldment base assembly. If that base is not square and flat, and the rails parallel and square to the table, you will be shimming and jacking to get things right to no end. And if it is off far enough, you will be grabbing the plasma cutter to cut the welds so it can be redone. In my experience, sometimes it is better to do it right the first time rather than try and fix someone else's handiwork. And that oftentimes results in an overall time savings. It all depends on how good or bad the machine is that you start with. There is a limit as to what can be economically repaired. Most of what I do regarding CNC equipment is commercial. So I don't "forget time"... otherwise everyone gets hungry. ;-) Let us know how you find the frame and top, as far as level and square. For your sake I hope it is square, flat and true. :-) I see that table was made in Guangzhou. I was there last year. That is a very busy city and a really long flight. But I would not mind going back there. I know some engineers who live and work in Guangzhou. The Chinese people I worked with in that area are very friendly and very easy to get along with. They can get decent packaging/crating material if they want to. It is available. I wonder what it would cost to have a machine packed in a real plywood crate? There were two guys in Minnesota who were importing routers like that for a while in bulk. I don't know if they are still doing that or not.
