I'd also love to build not of these games, although I don't have the programming skill to attempt it. My skills are in building the cabinets and mechanical parts. If you have a cnc then that's really going to help your build.
I'm going to follow this thread, and would be interested in buying a kit with all the specialized parts you make and a working pcb to control it.
I just got a PocketChip from Kickstarter, it's a $9 computer that runs a Linux Debian build. 1ghz processor, 512ram, 4gb storage, Bluetooth and wifi built in. It might have enough to run a project like this.
