If you have time and are so-inclined I vote for build. I did my kitchen back in 2007ish (thread below) and am currently in the planning stages on one for my parent's house. As others have pointed out, it does require an extraordinary amount of time but it is very rewarding. One suggestion I will make though is to do something smaller like a vanity as a "test" to discover the ins and outs of cabinet building. Doing a kitchen is nothing more than building a bunch of small boxes. Some suggestions that I will make that will save you tons of time;
1) Used pre-finished-ply. Can't stress this enough. You do NOT want to be trying to maneuver a spray gun around inside a cabinet or facing 32 * number of sheets * number of coats square feet of finishing.
2) Have someone else make the drawers. Unless you are proposing making really fancy drawers with hand-cut half-blind dovetails you can buy a very good quality drawer to your specs delivered to your door WAY cheaper than you can do it yourself. Drawers like you see in a normal kitchen are commodities and there are shops out there that are setup to make 1,000 an hour. IIRC my kitchen had 19 drawers and I did all the stock prep, machine cutting of dovetails, assembly and finishing. This process took me a month. Save yourself a month!
3) Make sure you have a place to store all this "stuff". Once assembled they take up a lot of space.
4) It would really help to be able to spray and you need to make sure you have space to dry all that stuff you are spraying
5) Plan your work to avoid as many "changeovers" as you can. For me, it was really "expensive" in terms of time to switch from plywood mode to solid wood mode to finish mode back to plywood mode etc. Being more efficient with things like that is one of the key takeaways I had from my project.
It is a very rewarding project.
