Have you done any research on the forum and looked at some of the very capable machines if you are not careful you will waste a lot of money.

It shows you have not done much as you are looking at 25mm ball screws with linear supported rails.
for a decent machine for the size you are looking at you will need 1610 on X and Y and 1605 on Z also the square rails have come down a lot in price are are far better.

First start a build log with a new post to keep all the questions in one place and then design something in cad there is no problem copying other people designs and then you will have a much better idea.
The golden rule is don't buy anything until you have a design sorted then the wise ones on here will put you right.
Good luck with the build .
