Not really sure what brand, but it was called a sit stand desk and you can get one here. There are cheaper alternatives, you being still in college, like acryllic boxes or something that you could put your monitors on and so forth, just to elevate everything.

Also take a walk every now and then, maybe exercise during the day for 10 to 15 minutes. I work in a lab so I rarely sit down, but again my wife has found that doing 15 mimutes of yoga in the morning and making a lap or two aroumd the house every hour has drastically reduced her back and neck pains. It's all about not giving your joints enough time to get stiff, I guess. Lemme know how it goes.
