The problem you'll run in to is that you'll be charged full tuition despite not using nearly the amount of services. I looked at one (I believe in Illinois but I don't recall) that was over $60k for the degree, all online, with minimal access to your professors, and no rights to the physical campus.

Oregon State University has an online 2nd bachelor's program if you already got another undergrad degree. Not sure how 'good' the program is or anything though, and it doesn't look nearly as inexpensive as the GA tech program if I'm not mistaken: http://ecampus.oregonstate.edu/online-degrees/undergraduate/...
