A Wardian case is an archaic name for a fancy, self-sustaining terrarium. I'm referring to the nice, prefab grow chambers such as the ones sold by Dragon Agro Products.
As for lights and racks, I'd say aim for some shoplights and metro racks. For the lights, T5 bulbs would be a good energy efficient choice, since cost is not a major factor. As for the racks, the ones mentioned here in Darcie's grow rack primer work great - they're sturdy and very versatile, and you can add on to them with extra shelf and leg kits.
As for an aquarium type of thing, you could probably just go scope out the big tanks over at the local pet store. I would go for something like these prefab greenhouses; you could build a bottom for them out of wood and plexiglass (you can buy big panels of plexiglass for $20-$40 at hardware stores) and use it as a walk-in terrarium. It would be more accessible than a tall glass tank, and more durable to boot. You might also consider something like rlhirst's shower stall terrarium.
I dunno about sphere reefs, except that many of them are touted as self-enclosed and good for two years or more. That would definitely make a nice addition. I don't know about reptiles either.
As for ultra highland, I'm referring to a terrarium appropriate for culturing Nepenthes and other plants that naturally grow at very high elevations, where temperatures are usually cooler than the average household and high humidity is maintained. Basically, just a very expensive highland setup. :)
Keep us posted! I'm very excited!
