My first build plans, criticism welcomed
First of all I'd like to give you all a tremendous thanks for this forum, there's definitely not enough people out there with interests like ours so I'm glad to be a part of the community. I've been in the hobby of building computers for about 5 years but really hadn't thought of implementing that knowledge into a build for my car. Until that is, I came across mp3car. And it could not have happened at a better time too because in about a month I'm going to be buying a 99-04 Mustang GT. So I have spent the last week or so compiling a list of the components I'll need to build myself a rig.
So what I'd like to do is run my plan by you guys so I can get some feedback and constructive criticism on what you think. I'll begin by saying that I have a nearly complete understanding of PC builds in the home environment. I also have a good understanding of typical car audio. What I lack, is a solid understanding of electrical circuits and such. The concept of wiring the PC into the car's circuit is what I've had to do the most research on. Also I plan to keep this build at a relatively low budget, I'll save the expensive builds for when my knowledge in this hobby is much stronger. So just keep those things in mind while you are looking through my ideas.
So first off, my hardware list:
MOBO: JetWay J7F4K1G2ES-LF $120.00 Onboard audio & video, 2GHz cpu inlcuded
RAM: G.SKILL Extreme 1GB DDR2-533 $24.00
PSU: M4-ATX 250W Intelligent DC-DC $88.00 Let me know if 250W is overkill, but keep in mind I have no idea how much I'll be adding to this build over time
MONITOR: VM80L 8in LCD Touchscreen $175.00 If it fits, otherwise I'll drop down to the 7" model. Anybody know much about this brand?
CASE: VoomPC-2 $63.00 Will be going in trunk
AUDIO: Unsure at this point as I don't know if the Mustang I'll be buying will have the Mach audio system. If I remember correctly, Mach was an option, not stock on all models. So the audio setup on the PC's end is going to depend on this
EXTRAs: Will be running USB to the front of the car to a hub that I'll add seamlessly into the dash somewhere for flashdrives, keyboard, and game controller (the onboard graphics on the mobo aren't at all impressive but I know it will run my NES/SEGA/SNES emulators.) I'll also be wiring a reset switch from the mobo directly to the front of the car for those BSOD situations. And finally, I will eventually add GPS, Wireless and Webcam rearview in the trunk, all via USB.
OS & FRONTEND: I will be using a very gutted XP with the Centrafuse frontend.
Now, I'll explain how I believe I should wire it. Please feel free to correct any mistakes or misunderstandings:
I think that I should use thick gauged wiring for the PSU to battery connection, with a fuse in between them. I'll also wire the PSU into the ACC or IGN wire (I believe I understand the function of the ACC vs IGN, but should I avoid either for any reason?) Finally, I'll wire the monitor to the 12v & ground on a molex connector coming off the PSU (That's the correct way right? Should I add a fuse between them?) And again, I'm going to avoid touching on the audio aspect of things until I know what I will have to work with. But basically I believe that should be it or am I missing anything?
Thanks in advance for any feedback, and it's nice to meet you all.
