Jon,
Going along that route I would think you will run out of cash very quickly.
I can't give you exact items as most of mine will be different, as in ball screws.
These people have very good prices but you will need to find someone to give you the correct lengths you would require to be made.

I made the mistake of ordering machined ends on mine, but that won't cause me any troubles as I will just re-machine one of them.
Angular contact bearings for X & Y between stepper coupling and screw and Z between thread and pulley.

For electronic bits, if going for 3 axis, the you require 3 off of these.

Plus one of these if wanting it to run off a USB port on your Mach3 computer and if ever you are going to fit a rotary table driven by CNC.

Plugs and sockets + other bits can be obtained from these places.

For my computer bits I just searched on Ebay for a cheap 64 bit computer to run Windows XP for mach 3 and a 15" touch screen monitor.
These are just links to the ones I bought, you will have to search for your own

Plus a few other bits

You don't want to go using a wireless keyboard or mouse, it can interfere with the touch screen.

Small power supplies for case fans and the back end of the breakout board.

Main supply case to put everything in, yours might be smaller (or larger) depending how tidy you are.

These are just a few basic items, you will also need a 48 volt transformer for the stepper drivers and four steppers, which you can find cheap enough on Ebay, I was lucky, I got four steppers and my power supply from a good friend at cost.
On top of all this you will need lots of cable and thick pieces of ali plate to mount the steppers onto your machine.
I just can't list everything here, just most of the major stuff to give you some ideas on costs.
