I was in the market for a 240 and after looking at the oceanic pricing, I decided to purchase a tank form Glasscages. Glasscages will build it any way you want. Mine was per drilled for a closed loop system and the front and sides were made with Low Iron Glass, I think oceanic calls it Starphire, price that in an Oceanic.
Tank looks great. Adding water today for, leak test.
