Best Mods for a Mac-mini used as a Music Server

@sbank 

While I strongly suspect that your assessments & prediction [that I will eventually jump into the deep end of the pool] are absolutely correct, I am refraining from doing so at this point in time.  My nature is to be pretty fastidious with purchases, so I tend to dabble in the more shallow end of the pool until I decided whether or not to expend the capital to get serious.  In my mind, going Mac-mini is precisely that.  I know going into it that it is not THE way to go, but I do not have enough experience with the whole music server/streaming experience to justify, in my mind, going for broke.  I would be totally pissed at myself were I to drop $10~15k on a set up & then decide it was not the right choice for me.  Does that make sense?

Thanks for article!

Upgraded power supply makes totally good sense!  Any recommendations on where I could acquire a high-quality, linear power supply?  Honestly, I do not even know what a Mac-mini requires nor how much it can tolerate.

2018 Mac-mini w/ 6-core I-5 chip, 8gig RAM & 512gig of flash SSD - "brand new" Apple refurbished model!  In fact, I am leaving in the next 5min to go pick it up from the Apple Store.

Thanks so much for your thoughtful responses.  I will definitely take your wisdom into consideration.  I have "seen" a microRendo in my ruminations & googling...I will do some deeper reading.
