The correct approach is to put the hard drive in the closet with your network gear - away from your components and listening area. You can then stream the files (either via WiFi or Ethernet, depending on your hardware choice) to your listening area. The PS Audio DAC with Bridge does this without a computer (as does the Linn DS player, Logitech Transporter, and a few others catching on).
You can do this with a computer as well if you wish, though the one you choose impacts the desired results - especially if it has a fan, dirty power supply, and/or a spinning hard drive in it (which defeats the purpose of getting it out of the room). I did this with a Mac Cube (no fans) a few years ago, and I know some have done it with a laptop using a solid state HD (no moving parts). But it's still a computer in the listening room that I find distracting.
That said, I recommend to everyone looking into this to just bite the bullet and invest in the full integrated solution. For an interim tryout, you can use the less expensive Sonos or Squeezebox hooked up to the input of your DAC, but you will eventually want the integrated solution of a Perfect Wave, Linn DS, Transporter, or similar DAC.
Have fun.
