    ATX vs ITX?

    I have an ATX P4 MB sitting around. I was thinking of just getting a 2GHz P4 processor for it and going from there. Is there any reason why I shouldn't use it? Other than size is there any other advantage of using an ITX MB? Heat? Power consumption? Other?

    I'm sure I'm not the first person to ask this question. I did a search and could not find the answer to this question.

    The biggest problem will be your choice of processor, not your choice of motherboard. A 2GHz P4 eats a shedload of power and produces nearly a shedload of heat, whether it runs on an ATX or ITX board.

    Size is the only real advantage of ITX over ATX.

    Have you looked in the FAQ yet?
    How about the Wiki?

    Thanks for the input. You confirmed my fears. So, where is a good place to start as far as processors? I really just want to run XP pro, some sort of MP3 player software, and Delorme Street Atlas for navigation. I don't think I need any thing to powerfull. I just don't want to have to wait a day and a half for boot up and launching programs. Please point me in the right direction. Thanks!

    i have a p4 1.7ghz and it doesnt even have a fan on the heatsink..and its never overheated. It depends alot on location and such.

    Try it..if it gives u fits then just change to a better choice for MB and proc later.

    1.7GHz P4 thermal design power is 63.5W. Source : http://www.intel.com/design/pentium4...hts/249887.htm

    In my book that is a lot. But then my entire system, including screen is something like 25-30W, so each to their own.

    I'd make sure you are ok with that software and how useable it is on a small touch screen. In the past, their software was horrid.

    Perhaps you should start here: New to CarPCs? Don't know where to start?
