Check out your campus bookstore or your academic department for specific campus deals.
However, you can get educational discounts directly through IBM, HP/Compaq, Dell, etc. They just probly won't be as good as if you get a special deal that your school has set up.
Lastly, don't expect your school to have a gaming laptop. Your best bet for that is to configure an HP/Compaq or Dell, since IBM doesn't really go towards the gaming side. GL
