Any brand new, clean PC is pretty cool with me. You just need a clean PC with any product and OS. We all have our preferred choices, and the kind of specification you need to see in your design system.

For me, I will recommend MAC laptops. It seems more secure to me than Windows. But when installing an OS, you should make sure you get it from a licensed and direct store in order not to get your PC infected even before you start using it. Most strong system viruses, like clipboard viruses and others that target crypto-related applications and extensions, have always been confirmed to be from infected OS.
