It depends on what your end goals are. If you are looking for a stripped down race car then a shell may be right for you. If you have your sights set on a rare or collectable car that is going to be a nuts and bolts restore or heavily modified pro-touring then maybe. If you are looking for your first project and want a car that you couldn't afford in running condition, then definitely not a shell.
It doesn't matter if it is running or not, what you want then is as complete a car as possible. A shell will nickel and dime you to death trying to complete someone else's half finished project. With a whole car not only will you have all the little bolts and brackets but you will have the added benefit of seeing what the completed car is supposed to look like. Even if you are going racing, with a whole car you can decide on what to take off instead of trying to figure out what you are missing. Plus, you said in another thread you didn't have mechanical experience and it is easy to get in over your head so tearing a car down can be just as educating as building one up.
