    one too the next item :-), Power sources. I was thinking of the M4 one but now thing the Pico 150. The pico 150 is a 24 atx connector and the M4 is a 20 pin. there is a significant power difference between them but both i think are more power then i need so that would be good. According to Asus i need a 400 watt power source but seems people are using alot less power to run the board.

    I just checked my M4-ATX; it has a 24-pin connector. I believe the M2-ATX has a 20-pin connector. Both have 4-pin P4 CPU connectors, too.

    No, it has three screwposts you wire into. There's no provision for an adapter, so I made one; here's what I wrote about it in post 75 of my worklog:

    12V Adapter

    Some time back, I bought one of the Coleman thermoelectric heating/refrigeration units that keeps food hot or cold, depending on which way you run the power. I hardly used it, and then switched to the Scion xB. In this smaller vehicle, the big cooler took up half the back seat, and I went for a smaller one that fit the smaller car. I'd about decided to give the original one away, and right about then it came time to test the CarPC on 12V. That's when I remembered that the hot/cold unit came with a 120V to 12V adapter with a socket for a standard lighter plug. Very useful, and it'll run a load up to 5A. Here's the way it looks:

    . . . Coleman sells the adapter alone for about $40 on their site, but they're available elsewhere for $25. Lower-amperage units are lower cost.

    Then I wired a cable that ran from my M4-ATX to a cigarette plug; that let me test it in the house, and I could also test it in the car even before I did any car wiring.

    By the way, a friend found one of those car cooler units in a thrift store -- with the 120V/12V adapter -- for $10.

    i just noticed that i order the wrong ram. went to get 4gig but got 2 gig. Oh well 2 should be more than enough for what i am doing. I went with the PICO because i have the carnetix to regulate the power and then i can bring it inside if i want to and it will work with my TV. it is really fast, between 10-15 sec into get fully booted into windows from cold and Centrafuse load time is down to about 30 sec from 4 minutes with my old PC. just have to get everything running as a shell and see what happens there.

    This I would really like to see. Can you make a video? What version of windows?
