Music server questions


I am looking to upgrade my source from a standard laptop. I play mostly flac and Tidal high def. 

Budget up to 2k.

Features I would like if possible. 
Use a monitor and keyboard with it. (is this possible?) 
Optical output. 
Internal hard drive or use with external Hard drive. 

Anyone have suggestions

Another route could be putting something like the Mutec MC-3+USB between your laptop and DAC. That particular unit reclocks, has galvanic isolation, and has SPDIF coax (though not optical) outputs.
