Curious about the choice of the Mac as a home server. I feel like an off-lease x86 usff pc, at roughly half the cost, would be more useful as a server. Pre-RAM-crisis you could get one with 32GB of RAM for like $240. My main home server is one of those HP ProDesk, running Debian.

Different people are sensitive to different things. I still find my 6th gen ULV i5 and 8GB of RAM tolerable.
