overflow box and skimmer advice needed - newb

[fotofeend]

Im having some "growing" pains with my newer 70G reef tank. Want to get rid of the Fluval canister I acquired with it and go to a sump and skimnmer. i dont have a drilled tank so i will need to use an overflow box. I am looking for any suggestions on style or type of overflow box and possible skimmer combos that have been successful. I am looking at a Bubble Magus skimmer but don't know anything about the overflow box.
