@bill_k this has a fan but very quiet, not an issue. Just install Roon, maybe a USB driver if vendor provided for DAC (that is the case with my Topping DAC) and good to go. Windows based but lots of headroom, can be used for general purpose computing alongside Roon as needed. Best to opt out on as many Windows setup options as you can in order to preserve compute power for what matters. Initial Windows set up may take an hour or so depending but went smoothly for me. I was up and running with Roon is less than 2 hours. 47000 tracks in my library including local storage (external USB drive) and Qobuz. Lightning fast, very reliable, sounds great. Nothing left on teh table with Roon here IMHO. Cheers!
