Laptop in the car = Asus EeePC, Linux

I'm hoping to get a Mac Mini under the TV to use as a media player, however it's white, everything else is black, and my wife likes things to match.
I'm trying to get everything centralised on 1 server, but it's finding the right O/S. One of my options is another Mac Pro running Parallels so that I can still keep my phone system and web server operational.
