So I have a DAC; now what Player should I look at?


Im new  to Digital and have questions about what Media player to use with my DAC. The DAC is a Merging Technologies NADAC ST-2 DAC. I’m not sure where to go next. I need a media player, a MAC, Laptop, Roon Nucleus+, ????? 
Ideas n thought are welcome.

I’d like it to cost less than $1000 and perform like it’s more than? Realistically I have no idea? A fanless server with upgradable solid state or hard drive. Ethernet connected.

Besides getting a Mac Mini or something, cheapest I can think of that can be a Roon core is the ELAC Discovery Music Server.
Cheap is not the necessary... I'd prefer it to be less; but I have a top of the line DAC, and set up so I don't want to cheapen the experience; just don't know what to look at. If there were a Mac Mini (Guide to using Mac Mini as a Music Server) I'd read it but Roon Nucleus+ looks good at $2400 as well. 
Can’t really beat the Bluesound Node 2 as long as you have a good DAC.....

It does it all and acts flawlessly.
IIRC the Bluesound Node 2 has a built-in DAC. Why should the OP pay for another DAC?
