You show a "Cigar Lighter DC/DC PSU" for your screen. Most screens don't need a seperate power supply. A Liliput would require regulation, but it comes with an egg-shaped regulator. Xenarc screens can wire directly to the car's unregulated wiring, and on an ACC line it would turn on/off with the key.
You're going to want a powered USB hub. Most USB hubs requre 5v power. There are point-of-load power supplies in the store that would be perfect for a USB hub and your optical drive (See #2 below).
The drive will probably require 5v power. You can get that from the powered USB hum or another 5v power source.Question 2) Can I usb self power a 2,5" optical drive such a pioneer DVR-K06 (DVD/CD writer)? I want it in my dashboard, so I have to link it by usb cable.
If your battery is strong, you shouldn't need to. A better battery is never a bad thing, though.Question 3) Do I have to upgrade my battery? (maybe with optima yellow 55 Ah) or it will work fine untill I use the system only when engine is on?
To my untrained eye, that appears to be a voomPC case with their branding on it.Question 4) what do you think about this case? http://store.mo-co-so.com/index.php?...products_id=17
is it comparable with voomPC?
Thanks a lot!!! Sorry if I have written too many question.

Here's a good "starter" FAQ: New to CarPCs? Don't know where to start?
It's in English, as are most of the FAQs. I know you're Italian, so I don't know how well you can read English.
And welcome to your madness.
