Looking for a music server, sans DAC.

For music playback on my primary system I currently use a MAC Mini into a Bryston BDA-1 DAC via an Audiophilleo USB/SPDIF converter. I am considering replacing the MAC Mini with a Music server that can access redbook quality AIFF files from an external hard drive, either downloading them to an internal drive or playback directly from the external one. The ability to download CDs directly onto the internal drive is also desired. I do not stream or download music off the internet except using my Macbook Pro laptop computer on a secondary system.

I look forward to hear from anyone familiar with the Bryston BDP-1 regarding how it will work for my application? I would consider purchasing one used should I be convinced this the best route. 

Also asking for advice on other music servers I should consider given a budget under $2000. If said server has a CD drive for downloading that would be a plus, however I could use the Macbook Pro for this.

Are there servers that can accommodate an external CD drive for downloading?

Thanks in advance for any help with my search.
