Proposal for first CarPC - Opinions and suggestions wanted
I've been lurking for a while now, and am in the process of designing my first CarPC. I have a list of parts, and would like opinions from other people on the system.
I am looking to have the system do GPS navigation, AM/FM/XM radio, FLAC/MP3 playback, play DVDs and stored movies, and do some low to moderate-end gaming. For all those curious, I don't plan to play games while driving. I do a fair number of road trips, commonly with at least one other passenger, so that aspect would be more for their convenience rather than mine.
In the future, I would like the system to interface with my car via OBD-II and process video from a dash-cam.
With that, here are my proposed components:
CPU: Intel Core 2 Duo E7200 http://www.newegg.com/Product/Produc...82E16819115052
Motherboard: Gigabyte GA-G31M-S2L http://www.newegg.com/Product/Produc...82E16813128078
GPU: Jaton 8400GS http://www.newegg.com/Product/Produc...82E16814139018
RAM: 2GB DDR2-800
LCD: Lilliput 7" Touchscreen http://store.mp3car.com/2008_Lillipu..._p/mon-016.htm
PSU: Opus 320W http://store.mp3car.com/OPUS_320W_In..._p/pwr-024.htm
GPS: BU-353 http://store.mp3car.com/BU_353_Weath..._p/gps-002.htm
DVD drive: something
AM/FM radio: something
XM radio: something
OS will be Windows XP, front end most likely RR, GPS software IG4.
Now I know this is an absurd amount of power to put in a car. Here are my thoughts on that:
I want the system to be capable for future expansion and capabilities, and also want to be able to multi-task (i.e. GPS running in background while dash-cam is running and DVD is playing). Furthermore, all the components have been selected because of their low power aspects. Running it through a few power calculators, I've obtained estimates of 200-225 watts power consumption, which I think it reasonable to overkill. Nevertheless, I decided on the OPUS 320W to have extra headroom as well as for it's startup/shutdown capabilities.
The micro-ATX motherboard is fairly large, but smaller than others at 9.6x7.6 inches. I plan to put the computer in my dash. The screen will replace the current radio, as that spot is low on the dash, hidden from the sun and very visible for the driver and passengers. The motherboard and power supply will be behind the screen. There is an opening of ~10.5x9 inches behind there, as I moved a few relays and harnesses out of the way.
As for cooling, the area that I plan to put the motherboard and power supply have air ducts below, to the side, and above, as well as openings to the passenger compartment. For the time being I will just have fans, but if cooling proves to be a problem, some of those air ducts may be modified to produce more moving air.
For power, there is an empty distribution block just to the left of the driver's feet, with openings already connected to the battery which I will be utilizing.
FYI, the car is a 98 Chrysler Sebring LXI (coupe), similar to the second-generation Eclipse.
Thanks in advance!
