How to take out animals in minecraft?

I play on a super-flat, creative, peaceful world, with no structures. I really like buildings and I hate it when stupid animals get in my way. I want a world with zero animals so i can just build my stuff. How do I do this?

Which of these PCs is best for video editing?

So i'm on the hunt for a PC for video editing/c4d rendering/gaming(mostly minecraft, gmod), and I need your opinions on these to conclude which one would be best. I'd like to say, in the future I would like to upgrade, but the first PC doesn't have compatibility with intel processors, and I hear they are better for rendering. The second one however has far better graphics, but only a dual core processor, despite it's an xeon. I'm also taking into account for money, so if it's to get better for your money that's good too. I'll let you take a look for yourself.
