Yes, you can swap it to a DC/DC power supply.
I just got a Shuttle XPC SS51G for free and would like to know if it would be a good starting point for a carputer, atleast just to get some experience before buying something better.
It is a 1.8ghz p4 processor. Honestly, I don't know too much about how to build computers but automotive fabrication is something I have experience with. I just need to know if this mobo and/or attached hardware is capable of being used in a car pc application.
I would like it to do (for now):
I know if I could get those three working, I'd be much more inclined to jump headfirst into a more complicated and expensive setup. Could I use everything in this Shuttle, but swap the AC power supply to a dc/dc?
I would really appreciate any help anyone is willing to give me!
I also have one more question, it may be dumb and obvious (hope so):
Toyota FJ Cruiser.
"Double-DIN receivers fit in the 4" tall opening found in many Japanese and American vehicles."
"Euro-DIN" stereos attach from the front through the 2" tall rectangular hole in the dash, sliding into a metal sleeve that attaches to the front of the dash.
Since I have a double din, if I buy the double din installation kit (like from Scosch) I will have adequate space for a 7" screen? I can't seem to get a straight answer on if the screen will be too big for the opening or not. Also, I cannot find any threads with another FJ already having this accomplished.
to answer your first question, yes a p4 1.8 ghz is ample power to do what you want.
secondly, the reason why you can't get a straight answer is because not all 7" screens are identical in real estate ie.. width and height, but are very close. This is something you'll just have to see for yourself by sizing up the components on hand.
They're not all 16:9. There's widescreen, cheap knock offs, etc.
