I agree with Reubent that the Mini is a great way to easily get into a music server. You don't need a particularly fast processor or a lot of RAM to run iTunes but the internal hard drive on an older Mini is likely to be quite small. Ripping your CDs to AIFF or even Apple Lossless can quickly fill up a small hard drive but it's very simple to add an external USB or Firewire drive. Decent 1 terabyte drives are now not much more than $100 and will hold hundreds of CDs.
Some help setting up a PC based audio system.
I want to transfer my CDs to a computer and use this as a front end. I have a friend who has an older MAC MINI he is willing to give me. I really don't know alot about computers so I wanted to know if an older one would work alright for audio. Is there an operating system that works better than others? Is Itunes OK to use or would another program work better? I purchased a Wyred 4 Sound DAC2 so I could use the usb input. Any advise would surly help. Thanks, Paul.
