Honestly I have not even finished setting up my first SW tank and i know all around 80 bucks would be hard to set a Nano up in SW esp reef. I dont want to take away from the reef crowd but I want to suggest since your going to be away at college, to make things easier for you and step into the planted tank world. There are many more possibilities and fits the budget you have MUCH better. I recommend looking at plantedtank.net at some of the tanks people set up, I myself love planted tank looks and you can really get a nice nano going for that price range with everything included in your budget. There are many methods at keeping planted tanks, I've kept nano's with a simple desklamp with a LED bulb in it, many use CFL's. You can stock it with freshwater dwarf shrimp!
A awesome tank for this setup are ones ive recently seen at my LFS, deep blue makes these nano cubes that are rimless and super sweet looking.
Look up some ADA planted tanks for a idea if you need some reference. PM me if you want to know more, and i know how much time college can take from you, i start tomorrow morning :(
