None of that really matters for a home media server. Even the limited SATA ports, worst case you have to grab a cheap expansion card.

Power consumption is a much bigger concern, a purpose built NAS is much more efficient than a random old PC.

With the amount of alternatives it’s also very likely that you’ll find one that you genuinely prefer over Coca-Cola or Pepsi once you give them a try. I did not start buying Fritz Kola over Coca-Cola because of any “feature”, and not because it’s German either. I just tried it on a whim ages ago and preferred the taste, so that’s what I’ve been buying since.
