Very cool, reminds of my friends setup. He has a 2.0ghz Celeron, 512mb ram and 64mb video in his car pc... he also has a dts processor and his pc is hooked up to his car audio and because of the dts processor, he gets true surround sound when watching dvd's... his pc starts and shutsdown with his car also, and he's gonna mold his 7" touch screen into his dash in the near future... so far it only cost him about 1100$ CDN... and he has an 80gb hard drive in it... pretty cool setup... he's looking for gps software and the required hardware for it so he can use it as a navigation system also...
Cool setup man!
