Yes, kinda. If you are the type of person that cannot do any sort of diy project, then a tank isn't a good choice either.
Note that almost any store that sells plywood will cut it for a small fee ( $.050 per cut is typical ), so you don't need a fancy saw. Give them a list of sizes, and how you want the pieces cut out of a sheet ( and remember that a saw cut takes up about 1/8" of material). Especially if you're buying from a "big box" store, let them know that you will not accept any mis-cut pieces.
