What would be YOUR ideal set-up for a 150 gallon freshwater aquarium?

I saw this great-looking 150 gallon aquarium at petsmart yesterday and I was thinking about how nice it would go in my house. I'd like to know from everyone, what would be your ideal set-up. I want to know everything you would put in it. From fish to ornaments, air pumps, heaters, filters, lighting, gravel, to sand. EVERYTHING! Keep in mind it would be a freshwater tank. I would incorporate your ideas if you gave them. Thanks to all that answer!
