I'm familiar with MSU and Case. I almost went to Case, but ultimately decided not to because 1. its in Cleveland and 2. its pretty expensive. I'm from the Murder Mitten and I know several people who go/went to MSU. I would cross MSU off the list immediately, unless you want to work in MI after law school. But, if you want to work in MI after school you should be going to Wayne State.
Case's facility is excellent, the faculty is strong, the people were all nice. If you're comfortable in the Midwest I would go with Case.
MSU's facility is also nice, not as nice a Case's but still good, I sat in on two classes, and I went to a recruiting event. I wasn't impressed with students or the faculty. The career prospects at MSU are very poor. MI is in terrible shape, Cooley is 10 miles away flooding the market with grads, and the Detroit market is dominated by Wayne grads. I was told by students at MSU-law that alums for before the affiliation with MSU, back when it was Detroit College of Law, are of little or no help to current students.
I dont know anything about Chapman.
