Audiophile quality streamer/server-in-one without a DAC. Does this exist?

I have a very simple system and want to upgrade my digital player which is currently my  5 year old Acer laptop.  I listen to Tidal a lot.  Sometimes I listen to high-res downloads (I only have about 20) and ripped FLAC albums (only about 100) stored on my Acer  and play them using JRiver 19.  That's about it.

My system is a Wyred 4 Sound Dac-2 plugged directly into a Wyred 4 Sound ST-500 power amp which is paired to a pair of KEF LS-50.  My Acer is my only source component.  

My question is this: is there an all-in-one digital source that can replace my computer as a server and streamer?  I don't need a DAC and I don't want several more pieces, peripherals, power supplies, etc.  I don't want to make my own.  My wife will tell you I'm not talented enough to do so.  I would agree with her.

Seriously, I just want one box that can do the same friggin thing as my computer but better.  I don't think I want a Apple computer either as I know that is a good solution for many.  

I feel ridiculous asking if there is something out there like this, but I either don't see it or my request is akin to looking for unicorns.  I'm ok with either answer.  Just hit me with the truth or some recommendations.

Thank you, Josh
