Like Bob, just exchanging parts now and then.
"Building from scratch" makes it sound a bigger deal than it is, it's not like you are actually building a custom design or something.
You just buy the parts, stick the stuff in the places where they fit and use a screwdriver to fasten everything. I don't think it's a lot more complex a task than connecting all the cables of monitor, mouse, dfp etc. to the back of a prebuilt computer.
Advantages are price and being able to select the parts you want, f. ex. a quiet PSU.
