Does it matter you in the long run what undergraduate you go to?

I like Cal Poly SLO because it is a great university at a great price. Besides, my family is low on money and i want to graduate with as little debt as possible. But then again, my dream college has always been Cornell. Do you think it would matter in the long run which university I go to? in terms of job opportunities, internships, etc.? I'm going into engineering btw. Thanks
