New case (again….!)
The build-your-own case plan wasn"t quite as good as it seemed, The computer fitted in but cooling wasn"t upto much, so I binned the idea.
After much searching around, it turned out that my local computer store (where I used to work many years ago) sells Mini-ITX cases, so I was able to pick one up today an hour after deciding to get one 
Great!
Here"s a picture of the case just after I got it home…
And 30 minutes later, it"s all in the case…
It fits in rather well, and looks better than I thought. It"s also got room to add a few custom bits inside, such as a 25 pin port or similar to allow a remote ATX power button, or a few other bits such as led"s while still having them built into the main case.
For the moment, I haven"t added my power regulator, which takes in the 12V and makes sure it"s 12V. Instead I am going to use a power inverter, and the 12V converter, and see if I get less noise through the speakers too. How converting ~12V DC to 240V AC then out to 12V is a good idea is anyone"s guess, but other people have been doing it, so it"s worth a try. Just in case you don"t know what the inverter looks like, here it is.
It will be wired up straight to the battery. I"ve also bought a motorcycle battery, as suggested on the thisstrife.com forums, which will be wired up to the main battery with a diode in between (to allow electricity in from the alternator but no power out from the motorcycle battery to the rest of the car) to allow the car pc to carry on working even when starting the car. I"ll update more when I do more…
