What kind of computer do you need for day trading?

I'm curious, what kind of computer should I be looking for if I'm planning to do day trading? Is it essential to have the latest and most expensive model, or are there certain specifications I should prioritize? Would a desktop be more suitable than a laptop for day trading? Also, do you have any recommendations for specific brands or models that are well-suited for this purpose? It would be great if you could provide some insights into this matter.
