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    

I actually have a brand new one for sale with a 1 TB SSD ($500 option) and I may consider even throwing in the .5M W4S i2s cable as part of the deal.

Is there any new info/recommendations on this matter since this post was created?  I'm looking for the same thing but I do not stream.  I just need a simple music server to connect to my dac/system for my pre-existing library which has a nice, user-friendly interface.
Nicodemix: lots of answers to your question since what you’re asking is just for a server, if I understand your question.  Price is always a variable.  
A few options I can think of off the top of my head: your computer can serve as your server.  I use JRiver software.  You can control the JRiver software from a JRiver remote on your phone.  All you’d be paying to is a JRiver fee ~$30.  This is what I do now.  It’s works just fine.  No complaints.
Another option would be something more audio dedicated.  If you don’t need cutting edge technology I would look into a Naim unitiserve.  It’s not their latest one but will meet your above stated criteria.  I have seen them for as low as $800 on Audiogon.  I think I will go this route in the near future. I have a naim preamp/dac/streamer now so I believe it will work together within the same app.  
There are others out there but all much higher in price.  Wyred 4 sound makes a server/streamer, $3k.  Aurender makes some well reviewed servers starting at $2k. Melco is another name to look into.    

Can’t  go wrong with Bluesound Vault but it’s a streamer too.  Good user interface, $1300. 

Hope this points you in the right direction.
Yes a few more details from nicodemix would help.  Where is your library stored?  How do you control content?  
what would the difference be between buying a Bluesound Node 2i and adding an external WD 2tb vs. buying the Bluesound Vault?
