Hi newlash09..congratulations for your new order it will definitely give your audio pleasure ..for operating system I am also not very adept with computer knowledge..i am just using it just as simple as Roon end point with attached NUC as Roon core, my hard disc are attached with NUC and for Roon control I am using IPad .
I stream music from Tidal and attached he’d.
You please just ask metrum guys to give you another OS sad card so that you can use it on other platforms ( other than Roon).

Thank you Sanj
Will contact the metrum chaps and see what they can suggest. They seem to be nice folks to deal with.
