Hey guys im new around here and just have been reading threw the forums lately. I used to have a kenwood double din in my car with the garmin nav but i wanna switch it up and do a carpc now because of the expandability and software. I am a little lost when it comes to this and i also look threw the stickies for recoomendations but they are a bit outdated. I would like someone to reccomend me a full pc minus monitor for under 600 bux.

Hard Drive
Power Supply
Optical Drives
Nav software-
Front end-
OP system-

I am looking for good performance in my system and reliablity. Any help would be apprecitaed.
