It's a great way to go, if for no other reason than it will give you a stronger relationship with your aircraft and thus make you fly more carefully. :)
That said, while assembly and setup is mostly trivial (the hardest parts are basic soldering and dealing with some open source configuration GUIs for some flight controllers), figuring out what to buy and where to source it is pretty challenging, especially for a first build.
