Understood that you are not a tech guy. And that you may not wish to be technical.
However, if you wish to build a pc then you must further educate yourself about computers: components, assembly, operating system, and configuration.
You want an "editing pc". What editing software will you be using? Most software programs come with a listing of hardware requirements. Usually in the form of "minimal", "recommended", or "best". You do not want "minimal" and you do want as much "best" as your budget ($730 USD) permits.
There are many details involved and you must pay very close attention to all of the details.
You must read reviews, User Guides and Manuals for everthing being installed. Including even the case.
There are always trade-offs and, of course your budget. A high end, high performing computer, for any purpose, will be costly.
You cannot and should not expect that just putting it all together that it will work.
There are videos online but many such videos are oversimplified, often wrong, and some even dangerous.
All the more so especially if you are not a tech guy and have never built a computer before.
You must have some experience with tools, proper procedures, and overall be very careful in how you go about doing things. Even though connectors and components have safeguards prevent improper assembly people still manage to break and damage components when putting things together.
Much can go wrong and even experienced builder's discover problems. And not problems of builder's own making.
My recommendation: Do not build your own computer unless you are willing to learn more
and find a knowledgeable family member or friend to help. And take the time to learn more about computers and building computers.
Your other options are to purchase a pre-built or have a computer custom built to your specs and requirements. Computers serve different purposes and even if they have common components there are variations that can make a critical difference. Common example being the PSU.
Why is a PSU important?

Summary: if you do not have some understanding of computers and components you could easily end up with a very expensive, sub-standard computer. Likely with all sorts of intermittent and varying problems.
And, if you attempt to build the computer yourself it is very likely that you will end up with a very expensive pile of damaged components.
Just my thoughts on the matter.
