Building a Music Server that will play all formats

I'm a mac person but want to build a stand alone music server for my hifi that will play all my MP3 and loss less files BUT most importantly will play flac files all in one simple player. I was thinking a Dell Zino connected to a TBD DAC. Any thoughts on this plan? Thoughts on player? Media Monkey or Songbird?

System: Vandersteen 5A, Rogue 180 monoblocks, Rogue Pre, VPI Classic.

Thanks!
