I am new to the whole CarPC world. I have been looking into it for about a year now, but have actually grown the balls to start. All I really want to do is have GPS, MP3's, and maybe vehicle diagnostics.

The PC specs are:

Intel Pentium III
866MHz processor
40 GB Hard Drive

While this be enought to run the apps that i need. I was planning on using Roadrunner as my front end. I am going to upgrade the RAM to 512 and add a bigger hard drive for the tunes and videos.
