Macbook Pro to Aurender

I am getting more comfortable with high resolution downloads as opposed to physical media (CD, SACD etc ) and am looking to expand my library primarily in that area. For this reason I am thinking of changing from a dedicated MacBook Pro that is used for audio only, ( 512 ssd, external 1TB lacie thunderbolt, running JRiver ) to a dedicated server such as the Aurender x100L or N100H. I would be running it via USB into an MSB Analog Dac. I will still use the MSB UMT+ transport for the occasional disc. Anybody have any thoughts about this move, positive/negative. Other suggestions or experience. thanks.
