The reef ready will have holes drilled in the bottom. For a 200 you'll probably have 4 holes. Two holes are larger and will probably take a 1" or 1.25" bulkheads and the smaller will probably take 3/4" or 1" bulkheads.
Bulkheads are used to connect plumbing outside the tank to the plumbing inside the tank.
The larger holes will carry water to the sump using PVC pipes or flexible tubing.
You'll understand much better after you receive the tank and look at everything.
Reef ready still incorporate overflows but they are normally called "internal overflows". Very glad you're getting reef ready.
