You can edit with a laptop. Get the best you can afford with a i7 processor and at least 8 gigabytes of ram and a 1920 x 1080 display. Certainly pass on Windows 10, I would go for Windows 7, I think the best OS ever, I know the Macs are going to scream. You can get a more powerful desktop for a whole lot less and it is more convenient to work on.
Thanks for the advice. After reading in to it I found a website saying that this is the min spec you need.
