What is the oldest mini (spec wise, i.e. G4, G5, CD, etc.) that I can get away with for the simple task of streaming music to an airtunes express and watching movies on a tv from drives (networked and local) as well as Netflix streaming? I currently have a mid 2010 15" MBP that I use as my main computer but haven't found an easy way to hook it up to an analog tv. I think I would basically use back to my mac to control that mini and stream everything from the network drives. Thanks for any help.
