Cold,
If you can make that chassis with hand tools, you can build a CNC router.
You will fall asleep waiting for a cheap machine to cut your parts at 8 in/min. and your plastic will turn to goo with a router moving that slowly.
I think you would be better off spending the $1500 on better components and your own labour to get a production quality machine that you will still be happy with after a week. As for drilling, if the hole has a diameter that is smaller than the diameter of the cutter, you can route the hole without the danger of using a drill chuck in a router.
