Streamer/server that works as a Roon core

The newer Innuos Stream 3 is not only a server/streamer running Roon core and player, but also a DAC (by adding the PhoenixDAC board), which offers:

• Dual Mono AKM DAC Chips with OCXO Clock plus FemtoClocks for Audio 
• Support PCM up to 32bit/768KHz and Native DSD 
• Independent Power Supply for Digital and Analogue Stages 
• High-Quality Gold-plated RCA and XLR Connectors 

@jrdavisphd roon nucleus one is what I use as a server. My Meitner MA3i is a roon end point using its built in network card, via audience Ethernet cable. 
As crazy as it sounds, Ethernet cable matters on roon core nearly as much as it does on the Meitner. Hopefully after this major new Roon release scheduled for today the resource utilization will be optimized and something as simple as nucleus one. 

Thank you all. Yes @audphile1 I have Shunyata Gamma cables on order for connecting my Zen Mini Roon core/server to my Meitner MA3i. It's also nice to hear from you and @tump350 regarding your experiences with the Meitner MA3i DAC/streamer. Interesting to read that the MA3i sounded better in @audphile1's system than the Innuos Zenith Mark3. Extrapolating from that, it may be that the Innuos Stream1 or Stream3 would not sound much better, if at all, than the Meitner.

My aim is to get a device to support Roon core/server functions that will have better processing capabilities than the Zen Mini, good though it is. 

I have considered building a NUC or purchasing the Small Green Computer sonicTransporter i7 (which I forgot to mention in my initial post).

I wrote the post with its question because it seemed to me that there are few companies that make streamer/servers that can work as a Roon core. The contenders appear to be Innuos, Atipodes, Grimm, Small Green Computer, and DIY NUCs.

@jrdavisphd slight correction…it was the aurender n200 that I was able to eliminate.
