I'll post some updates and pictures this weekend. I just installed the audio, video and data cables today. Tomorrow I will install power cables and hopefully get the computer parts into my new case.
I ran into some snags. No matter how small I tried to fit my motherboard, power supply and hard drive in the smallest case (term used loosely) I could make with plexiglass, the damn thing would not fit into the glove compartment. And I don't want to fab anything directly into the glove compartment.
I ordered a new ITX case for the computer and it will go in the trunk as originally planned.
You can keep the stock stereo, but there will be no room for an indash LCD. You'll have to attach the screen to the dash and run cables through the front panels to keep the stock stereo. Also, the only AUX in is on the front. You can look at
this thread to get an idea of how to mod/solder an AUX in into the stock radio so you can have a port on the back.
