Actually for the kids they want to play games. they dont watch movies much (they hate repeating movies) ...
and at the front seat , Navigation , emails , some office work (not me the driver , but the wife) ..
I was thinking a low power GTX 1060 or GTX 1050 ti , and a low power i5 or i3 CPU ... but I dont know about the case and vibration and heat when the car is parked ... this is my first time.
The issue is that with a normal desktop is things snap into place and are designed to be stationary. This goes for the GPU especially, that snaps in and has 1 or 2 screws securing it down to the case. The typical CPU heatsink is held in by push pins or has a backplate behind the motherboard where it is secured down to. None of these were designed to be constantly moved. The computer will work, it's a question of how long will it work though. It may be something wiggling loose, or if your unlucky literally breaking off there is really no way of knowing.
The other thing is can you car handle this level of power draw from a full on computer running? If im not mistaken the older Ford Crown Victoria cop cars had a beefed up alternator just to run all the stuff they had so this is something else you have to look into as you may run into that same problem.
As for movie repeats if you have netflix there is nothing stopping them from using the tablets battery power and downloading a new show before the new trip or if you let them hotspot your phone to it so they can stream it. Or even put new shows on it manually or from a usb stick.
From a windows tablet they can game, but not current AAA games. That is something to keep in mind, this is one of those something is better than nothing issues.
Simplist solution, don't install anything just hand them tablets, or 2 in 1 devices and hotspot. Let them download movies to it before, along with their games. There is nothing wrong with having to play less graphically intensive games for 10hours, there are plenty of them out there from current games being to produced to older titles. And if there is no good places to charge the tablets back there bring a big battery for it. And remember you can still charge it in the front of the car so you don't need to go too overkill on it.
