I want to design my own custom 404 not found page but i dont know how to set it up with smf? any guidance?

That would be something you could do through cpanel. Take a look at this link that will walk you through it- http://www.inmotionhosting.com/support/website/how-to/creating-a-custom-404-error-page

but by default if an SMF topic does not exist it would not use that 404 page.

http://custom.simplemachines.org/mods/index.php?mod=3969 would do that job.

If you're looking for a 404 redirect for your whole site, or just the directory it's in, look how you can do with htaccess.
