    IMHO fast boot times have little to do with the speed of the processor or number of cores and more to do with the design of the MB, Bios, OS, MB HDD sub system interface and type of HDD and to a smaller extent the amount of RAM if using Hibernate.

    There are times when you my want to listen to music with the engine off (waiting for Wife, GF or partner) or play around with or mod the system, that amount of power would be a killer.

    The system Iím using absolutely screams along and drawís a total of 35 watts including all Microprocessor interfaces, Digital radio, GPS and LCD screen. Thatís with GPS running, Digital radio playing, OBDII diagnostics running, and interface microís running hi speed data access to various sensors.

    With all sub systems running, the response to any hardware interface button or touch screen menu item is instantaneous. Thatís with an i3, I believe that later more powerful processors may draw even less than my older i3. Power dropped almost 8 watts with the same components when I changed to this later MB.

    edit: too slow. i guess this is just to add to what mickz said....

    i think you are really mistaken as to what a carpc does, and needs.

    speed:
    1. bootup:
    this depends on your hardware, and the way the bios is setup. the processor selection has little to do with this. there are fast booting boards and slow booting boards.. i can get a atom board that boots faster then a i7 board, and the other way around.

    2. overall speed:
    while there is a noticable difference between a atom processor and pentium, there really isn't much difference between a pentium and i7 (i have 4 pc's-- a atom board home pc, a mobile pentium laptop, a 775 socket pentium in-car, and a i7 gaming rig)

    but again, the way the that the system is setup and configured affects the speed more then the processor. with the right tweaks, i can make a atom board feel just as fast as a pentium..

    the difference between a pentium and a i7 is in very-very-heavy processing. like gaming, and autocad..

    doing things like surfing the web, listening to music, gps, etc is not enough to even get the pentium to break a sweat. i doubt you would be able to tell a difference just browsing web pages between a pentium and a i7.

    the board should be ok.

    the processor is overkill.

    the 8gb ram is complete overkill.

    i run 2gb in car, and it is plenty for my heavier-then-average carpc use(i use the carpc for realtime audio manipulation).

    also, if you ever plan to use hibernate, the smaller the amount of ram, the better. remember that when you hibernate, the pc needs to write all the data from the ram into the hdd. that can take quite a while even with 2gb..

    this is good-- the slot load type is the best for car use, as there is a possiblity that a tray-load drive could break while loading a cd on a bumpy road.

    i think that ssd should be ok--there are good and bad ssd's-- which can also affect speed..

    i am not familiar with that gps receiver, though, i believe that as long as it outputs nmea(sp?) data, then it should be useable with any mapping program. if it outputs it's own version of data, then it is pretty much useless. the bu353 is the most popular receiver here, and has been verified to work with all the available gps programs.

    Hi soundman, don’t you just hate it when that happens, however your point about SSD speeds not being equal among makes and chipsets is another very important point that I overlooked.

    Dear soundman, thanks very much for your details, I hope that I got before I buy.

    Anyhow, I am thinking now of selling the i7 and 4gb ram, and buy i5. Do you think this will be a good solution?, or it is better to buy another whole configuration from scratch?

    i missed your last post..

    the i5 would be ok, but still is pretty big for even the more demanding carpc's-- unless you are doing some really serious things in-car, i really don't see a reason to go above a i3.

    Hi all...

    Thanks all, specially Mickz and Soudman98.

    my updated project become:
    - Gigabyte GA-H67N-USB3-B3 H67 LGA1155
    - Intel Core i3 i3-2130 3.40 GHz Processor - Socket H2 LGA-1155
    - The rest is the same as before.

    I already tested it with M4-ATX PSU, and it worked fine.

    Unfortunately got stock with two issues:
    - Installing NavTools Multimedia Interface. I guess they sent me the wrong harness. But I have Lilliput 10.4 instead for now.
    - Connecting the Audio as I did not find the right place to connect the FM Modulator.

    My car is BMW 745i 2002.

    When I finish, it will my honor to post
