1. What motherboard?
2. Power supply?
3. Are you using a case? If so what type? If not how do you plan to support it?
4. Go ahead and tell us what screen you plan on using.
This is working off of the assumption you don't have a GPU already otherwise we are talking adapters.
1. I will pretty much say I have 2-3 computers that I was going to convert for usage into a carputer. I will have to check exactly what I have but I know they were Asus motherboards, one having a E8500 and another a Q6600.
2. I have several powersupplies that range from 400W to 600W. Ideally I want to stay in that range since the inverter is around 600W.
3. I am not too worried case wise. I have more than enough room to hide the PC, so I don't have to get a ITX setup. I would probably get a small mid-tower.
4. I do have one GPU that isn't being used - A ATI 2600XT. I also have two Gigabyte passive cooling 4850s in crossfire but they are in my gaming/daily use machine. I COULD upgrade and remove those 4850s but it really depends on the options I have.
5. The screen is a Pioneer N2 screen. Specifications are here:
6.5 inch / 16:9
336,960 (1,440 x 234)
I honestly would consider a Lilliput to make my life easier but I have no more room on the dash with a Pioneer N2 and a Pioneer DEQ 9200. The only other option I would have is if I would build a mount and holder for a retractable monitor (20"-30") for the passenger side. However, that wouldn't be for a while considering the other projects I still have for the car.

Not sure it you can use more than one port on a motherboard with onboard graphics or not. Which would also be another option.
Would definitely require less power draw on battery/alternator and would require a smaller powersupply and enclosure as well as reduce heat.
I don't really need two HDMI outputs, I just need one TV out and one HDMI out. From researching last night, it seems that I can get that in one card. The ones you listed don't seem to have a TV-OUT. My question now is, does running the TV-out and HDMI tax the card? If so, which card would be the best? I am not really going to be doing heavy gaming or anything of that nature. You don't have to worry about the alternator/battery, I already sorted that out and they are fine. The battery is a deep cell optima yellow top so it has tons of room and I have a 250amp alternator to handle everything.
That converter box looks pretty good but from what I have been told, the quality can be hit or miss. Plus the "good" converter boxes are almost $300. Seems a bit out stupid for me to get that when I could get a GPU with TV-OUT for a small fraction of that cost.
