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