Question on Streamer/Dac and Roon

I'm fairly new to digital and am building a system that's both MQA capable and Roon ready. I currently use a 2014 Mac Mini as roon server + streamer connected by USB to the Mytek Brooklyn Dac+, which then feeds balanced into a Mac pre and amp. I keep reading the mac mini is noisy as a streamer and hence the post. If I were to re-engineer a bit there are a couple of choices I can make, assuming my original goals of MQA and Roon remain. 

Should I:
1. Get a Lumin U1 mini, which can act as a Roon endpoint, and feed into the Mytek DAC (ESS 9028)
2. Combine the streamer and Dac functionality into the Lumin T2. I'm not sure if this is indeed a step up since the T2 also has the same ESS 9028 chipset as the Mytek. 
3. Keep the current setup and be done. 

I use the mac mini as the roon server, and that comes to my last question. If I get either of the Lumins, they would be the roon endpoint. I will still need the mac mini or a NUC to act as the roon server. I'm not able to comprehend the point of a streamer other than acting as an endpoint for Roon, sort of like a catcher to what Roon throws at it. If Roon is going to be the front end, does the Lumin really provide me with a benefit? I like the Roon software and being a lifetime member unlikely to switch over to the Lumin app. And I do not have Lumin dealers nearby to audition them. 

And some footnotes. I dont want to spend too much, the Lumin U1 mini or T2 is the max I would like to go, if I can justify their point of existence within my system. Also, not a Nucleus fan if a NUC can do the job for cheaper, and so can the mac mini. 

What would you do and why?

When I mentioned "noise" I meant the digital one that others speak of, I personally have not heard the fan of my mac mini come on for the files that I have on it, around 10K. And no DSPs as well. 

My objective is to understand if I'm missing out on the sound quality due to the setup I have now, while at the same time not invest a boat load to attain nirvana. If the mac mini is the compromising factor then for around 3-4K move up to the next level. Thanks for the feedback so far.

I would Stay with your current Mac mini..  Don’t under estimate how good a music server it is. try to split up ports by using thunderbolt and USB. Have you tried an LPS for the PS ? I’m not advocating that as I have not tried it myself on the Mac.. but I am using a SMPS in my other music setup with no negative affects, that was compared to a LPS of the same rating. many swear by the LPS effects on the mini. I use a MBP and a MBA bettering all the various CD players and transport/dac’s I’ve tried, but I did enjoy the Cary 306 SACD player and used it as a DAC for many years, just never trouble free.

Thanks all for your inputs. Anybody has experience comparing the Mytek Brooklyn DAC+ vs the DAC in the T2?

+1 on the SGC Sonic Transport. I moved off a Mac Mini to that and have been purdy happy.   I am a believer now in getting the Roon Core onto a dedicated music server device.

You could do this combo for fairly cost effective Roon server,endpoint.https://www.smallgreencomputer.com/collections/audio-server/products/essential-server-player-solutio...

Notice how most that moved away from MacMini or similar are happier and that those suggesting sticking with it, haven't tried the more effective alternative?
Running Roon core in a separate room on a Nuc(cheap!), Sonictransporter(medium cost, but play and play) or Nucleus(higher cost) with a renderer/endpoint in the listening room is the solid approach. 
With renderer network player is a topic well covered in many threads. Agree that a good LPS on the renderer is a key factor in getting high sound quality. 
FWIW, I went from MacMini to Sonore microRendu w/LPS to Sonore opticalRendu w/LPS as Roon endpoint and run Roon Core on a SGC Sonictransporter i5 in the other room. Library is on a Synology NAS. Details on my system page.

Straighten out your issue before worrying about DAC upgrade. Hell, in another couple of months, something newer, better, cheaper will always be coming...
