I have now finally finished a tutorial for my XBOX 360 Power Supply to 12V Accessory Adapter project and it is working great with my CarPC (mini-computer) which draws approx. 4A. I have also tested this adapter on a 6.5 Amp blower motor, salvaged from a R.V. heater. The blower actually spiked over 10 Amps on start up with no effect on the power supply and adapter. This project will be useful for running all my 12V accessories indoors from my cell charger to my portable DVD player.

Here's a link to a youtube video i made on my first test adapter:
