Hey, sounds like a neat setup, what sort of case are you planning on running?

**DocHoss** · 05-07-2009, 10:01 AM

I haven't really considered case options yet. I think a small case may fit under my back seat. It has a pretty large storage compartment when you fold up the bottom of the seat. I haven't gotten around to measuring it yet, but I'll start doing that "numbers" stuff next week, after school is out.

Strife, the M4-ATX has a startup/shutdown controller built in, doesn't it? Am I reading that wrong?

Also, does anyone know a good place to find power draw from components (how much wattage does a hard drive, mobo, processor, usb hub, etc. draw)? I'd definitely appreciate that!

Also, I haven't heard anyone weigh in on that screen that I found for cheap from an mp3Car user. It's made by a company called Digital Worldwide. Anyone have experience with them?

Sorry missed that part.

I don't know about the used screen but a typical Lilliput 7inch screen will draw 10 watts @ 12 VDC (0.833 Amps) max per there website.

As far as the rest of the computer, I have the same board. I calculated it out to about 125 watts worst case including all accessories. That’s just under 10.5 amps at 12 VDC.

Here’s a cool calculator I think you will like.

That calculator is great! It says that my setup with the fatty mobo and processor I have here will draw right at 235W with everything including a PCI-X16 video card and the PCI-1X sound card (included with the mobo). That is marvelous, because it means I don't have to buy any of that, which cuts my price structure WAY down. The M4-ATX supplies 250W, and I won't be pushing the system hard at all (may actually underclock the cpu), so it should be no problem.....right?

Guess if I did have to buy the Atom mobo/proc setup, it would be not even close to maxing out, so that would be a good solution if this didn't work. Not too pricey either.

I don't have any experience with that brand, but I'm planning on a Lilli off eBay for my setup.

If you Google your part number you can usually find some specifics. Western Digital I know is real good about their power consumption on their website, and sometimes Newegg has specifics as well.

With a 90W power supply and a desktop hard drive, you should be just fine on that 250W M4.

For those who may be following this thread, I've acquired most of the ESSENTIAL parts for my initial setup, including the mobo, processor, memory, and hard drive. I really just need the power supply and screen and I can begin the assembly and software installation process. Still need to get components like GPS, but that can wait...I'm excited to get started, and bummed to see these other parts just sitting around not doing anything!

I'll start the worklog and pics just as soon as I can get the build started.
