Would this be a good starter system for streaming?

I am new to streaming so looking for valuable input. I am considering purchasing the following:

Music Server - Small Green Computer - Sonictransporter i5 with CD ripper
Music Streamer - Ultrarendu
DAC - RME ADI-2 

Was also considering the optical versions. Want to run as a ROON server.

This will be used with KEF 107.2 speakers, Macintosh 34v & 7200 amp.
i have a fairly large CD collection that needs to be ripped

Would something else be better in the $5K range
