It's an All Glass Aquariums 90 gallon megaflow. The big black box that you see in the pic is the built in overflow box. The tank is pre-drilled on the bottom. I bought AGA's plumbing kit for it which comes with the standpipe, the return pipe and the bulkheads. Setup in the tank is super easy.
I paid $649 for the tank, stand and the glass top, but that was here in Alaska where the prices on stuff tend to be higher due to shipping costs to get things up here, so you could very probably get it cheaper. The megaflow plumbing kit is another $49 from DrsFoster&Smith.
For lighting I'm using the Coralife Aqualight Plus which is 4 X 96 watt PC
(2 X 10K and 2 X Actinic) and has the 4 lunar LED
's built in. External ballast so the heat isn't too bad. Less heat than the 2 X 96 watt that I have on my other tank but has the ballast built in to the fixture. Was a pricey light solution though, bought it locally for $500
