Vinegar is a safari extension that gives you premium’s features. I’m almost certain it can do at least 1080 if not higher.

I have a node 304 case with an itx board and I wish I’d have gone with something bigger with more expansion slots. Some sata ports died on me so I installed an hba card to give me more. That means I can’t add a 10g nic or a video card for hardware acceleration or…you get the idea. Ideally spend less money now and experiment, then in the future you’ll hopefully learn what suits your needs.

Understand that this is a rabbit hole where you’ll hear a million opinions. If you’re just starting out, I’d recommend keeping it simple. It’s been a while since I looked at what’s new, but I’d look at truenas scale or unraid first.

I personally use truenas core (based on freebsd) but truenas scale (based on debian) opens up more options like docker that might be useful in the future.

I recommend sticking to hardware you already own until you run into something that you can’t do. Then you’ll have a better idea of what to look for and how everything works.
