I want to create a "suitcase PC" out of a mac mini. The display would be USB powered, so would the keyboard while the mouse would be Bluetooth. The mac mini I'm looking at is the one viewable on apple's site right now - unsure of release date. If an older version would be more suitable, that would be fine - as long as it supports my intentions. How do I wire dc power into the thing? DC to AC inverters are out of the question. I have found other guides to wire the board to a dc power source, but there are no further instructions with regard to voltage, amps, and regulation of the power supply beyond that. I have a basic understanding of electronics and circuits, but soldering together a PCB is beyond me. I would prefer a build-once no-maintenance solution - otherwise I would find a dc-powered PC with thunderbolt and build a hackintosh.
