Ahh ok.. I was wondering what that was.. it didnt occur to me that it was the computer.. for some odd reason I thought it was a CD stacker.. jesus I'm stuck in the 90's even though I use my Iphone for my music >.<

How much did the mac mini set you back?

I've thought about using a laptop instead and having it on a mount.. but the pics i've seen of peoples laptop setups looks really invasive in the cabin. Your setup is really neat and tucked away.
Having the screen coming out of the middle of the dash (where there stereo sits) would be cool. Might look into that. I want a roof console the runs down the middle of the cabin and not across it so im not sure how a screen would fit into that without it looking crappy.
