You have a different philosophy towards computing power in a car. Usually the principle is "minimum MIPS for the job = minimum power drawn = minimum heat dissipation". Electronics cool, we cool, ek dum pheet! Waste not, want not.
2GB is seldom essential even in a desktop, unless the applications one uses need huge buffers. So why use huge amount of RAM when one will use only 3 apps max which use small buffers?
Performance should be a concern if all you want to do is listen to music and occasionally watch video or use GPS. Remember, that was possible even with the old PIII laptops with 256MB RAM (I have an ancient Toshiba which is still chugging along in this duty)
Water cooling?
That would create more problems than solve! One fine day Ajay-bhai will find a puddle in the car and wonder who did it. It is appropriate in a games desktop, inappropriate in an environment which vibrates all the time.
Ajay, inside the cabin it will seldom exceed 35degC (~92F) when the PC is operating and the A/C is off. If it did, it will be too uncomfortable for you to sit in the car. What matters is the temperature where the PC is mounted and whether there is adequate draft to remove whatever heat is produced. All the devices are made to work normally till 50degC
device temperature provided they are not in a hermetically sealed box. Even there the metal of the box is used as a heat sink extension. Ever seen an HU fail due to ambient heat? The environment inside the dash is cool enough and drafty enough that all electronics mounted there stay cool enough not to need fan cooling. And then, you would be using A/C most of the time, right?
SSD: It is better to keep the OS and apps on SSD, and all data on HDD. That way you lose data on HDD crash (replaceable from backup) but need not spend time reloading OS and reconfiguring everything. Same 'fit and forget' principle as HU: unit stays, content comes and goes. And yes, booting is way faster with SSD.
DVD drive: the slot loader you found should be good enough. Don't worry too much about mounting damping etc. The built-in damping is sufficient, unless you want to watch movies while doing cross-country or stunt-jumps. Actually, cross-country is benign - problem is when you hit potholes.
