it depends on what you plan to do with the machine! If you are going to
machine pocket watch parts, you don't need much space there. If you
are going to bore engine blocks, you probably don't have enough.
But, you should be able to get a decent size Jacob's chuck on an MT3
arbor, put a 1/2" jobber's length drill bit in it, and still have a
couple of
inches below the drill tip. That is generally going to be your longest
tool. One other long tool is a boring head with a relatively long boring
bar in it.
