I have a 27" iMac BTO on order to replace my windows PC that I also use as a semi-HTPC. I have a pretty healthy backup collection of my Blu-rays on my current external drive I use with my semi-HTPC. Will the iMac be able to bitstream to my receiver? What about having to use bootcamp or Parallels? I know I'll need a thunderbold to hdmi cable. Can order from monoprice.
