That snap-on dc-dc isn't regulating the 12v rail, as far as I know, so you'll need a 200w 12v regulator in front of that (as your car can put out more volts, which can damage the computer).
Before anyone says "search", I already did but could not find anything. Here it goes. I just don't have the money for an Opus otherwise, I would definately get one. I don't care about shutdown time and surviving crank. I don't mind pushing a button everytime I get into the car to turn it on. So is it possible for me to just use the 200watt snap on dc-dc power supply? Do I have to use anything else? Thanks in advanced.
Run to walmart, spend 20 to 35 dollars on a DC to AC power inverter, and plug your normal computer power supply right into that. Not the most efficent way, probably won't survive crank (Though it might), and you'll have to manually turn it on/off each time. Also might put some noise in the line... If you do this, however, I would recomend running the inverter straight to your car battery instead of using a cig. lighter socket.
Check out this site, hopefully it will be live soon so people can order. I stumbled across it a few days ago working on my car puter. The ITPS looks really good for turning and powering systems.

i guess i am going to go with the inverter route, is it a garantee that i will have line noise with an inverter?
Naw, I've been using an inverter for a few years now. Had line noise at first, but just make sure you ground everything to everything else. That's how I got rid of it. Simple.
