Mounting motor under table?

Agree with what jonathan says just one thing to point out 2:1 10mm pitch is effectivley 20mm pitch. If you can live with this loss of resolution then it's a good way to go.

What's your main intended use.?

Edit: Jonathans comment about accelleration is even more important if you plan to do lots of 3D and intricate V carving. 3D and intricate carving is very time consuming, esp vcarving, with lots of very small moves required with the Z axis dancing around all over the place. The problem with low accel is the commanded feed rate actually never get's meet and therefore the cutting time increase's. On very large 3D jobs this can run it several extra hours or even days.!!
