Roon 1.7 Thoughts & Need Your Input

So, I finally decided to do the Roon "free trial" and utilized a MacMini dedicated to just running the Core. All other programs were stripped out of the OS. I found I really liked the Roon interface. Unfortunately, my computer didn't have enough horsepower to run the Roon app resulting in frequent dropouts. This MacMini has an SSD, 8 gb of ram etc. It does not have the latest and greatest OS but a  higher version than Roon requires.  I noticed the computer ran "hot" also. I did a system speed test and I have a very fast connection with a great router-modem set up. Would anyone comment on what they are using to successfully run the newest Roon version? Small Green Computer's sonic transporter, etc?
