Check out Bulk Reef supply site they got great DIY video's.
You may want to consider a second emergency drain as well. I would go with the herbie system very quiet when it's set. IMO

plan it out first;once a hole is drilled ,its drilled.think of the size of your return lines,and have the drain 1/2 to two times bigger.buy your bulkheads and figure the depth from the top of the edge of your tank to where your holes are going to be.aqua medic makes a nice overflow comb,where you can remove the teeth for cleaning.j&l carries it.if the tank is glass you might want to check out a glass overflow box,and make sure you use aquarium safe silicone(i use newflex 333 aquarium silicone.a tube is about $12 and you can order it from any glass company
