Any ideas what they might be using to mill the wooden enclosure? I have a few projects that need enclosures and it's been a few years since I looked but the CNC mills were still thousands of dollars.
You could just use regular woodworking tools to get it done.
If you really want to CNC mill something like that then maybe look at the inventables x carve.[0] I got to use a shapeoko for a while which was the previous inventables CNC and it was pretty OK.
I would highly recommend looking in your area for a hackerspace that may have tools like these.
CNC would be one of the better routes. Like you mentioned, the cost is a barrier. Luckily you can rent CNC time at some hardware stores, university wood shops and some local hacker-spaces. http://100kgarages.com/ can locate you a CNC and answer any questions you may have.
