I use Antec cases too. I build my own computers. Yes, I would say a bigger case makes less noise than a smaller one, all other things equal.

Other tips:

Get M2 drives, and not hard drives that make noise.

The graphics card in most people’s computers makes a lot of noise. I buy a CPU with integrated graphics to avoid that. If you are not doing video, digital audio programs don’t need a graphics card.
