I’ll apologise now for the tiktok link, i know how much this place hates tiktok but here is a woman who did a deep dive and found evidence that the company actually changed their logo and tried to scrub the existence of the Cornucopia from the internet to distance themselves from Bad PR.

Likely not the solution you’re looking for but a buddy and i link a folder via syncthing and anything added to one side shows up on the other.
Most of that will be budget based and long term goal oriented. Do you want a 4 bay nas with 10tb drives set up in raid 5 or do you think you’d want a two bay system with 5tb drives set up in mirror raid? Do you want to start cheap and get a second hand thinkcenter off ebay or do you want to buy a brand new NUC and put a 2tb M.2 and 16gb of ram in one slot so you can add the other 16gb later? Some nuc can take up to 64gb of ram and have two 2tb drives in them.

According to this it’s still planned, though time will tell.
To play off what others are saying i think a mini pc and a stand alone nas may be the better route for you. It may seem counter intuitive to break it out into two devices but doing so will allow room for growth. If you buy a creeper bare bones mini pc and put more of your budget towards a nas and storage you could expand the mini pc without messing with your nas. You could keep the pi in the mix for a backup if your main pc is down or offload some services to it to balance performance.
