I have a laptop case that is pretty big, as it can fit my PlayStation 4, it’s games and my laptop. However it fills the majority of my carry on. I was wondering if I could have my laptop case separate from my carry on and just carry it onto the plane. Or if I should just keep it in my carry on. I am flying on Delta.
Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking.

Delta allows one "carry on bag" and one "personal item" on board. The carry on bag is allowed to go in the overhead bins, while the personal item must fit under the seat in front of you. So it is perfectly fine to bring one carry on bag and your laptop case as a separate personal item, as long as the laptop case fits under the seat (I've never seen one that doesn't) and you don't have any other personal item (purse, briefcase, etc.).
