Well first of all, what makes you think you're better at LS exams than 95% of the other people at Pepperdine? Are you willing to bet $150,000 on that? I'd rather take the money to Vegas.
In your situation I'd go to Georgia State. Georgia's in-state tuition is incredibly cheap and I think if you work the system you can get it in your second year. Better yet, just move to Georgia for a year, work as a paralegal or something to make some connections, and then go to GSU and shoot for a small firm job. You'll be making around $50-60k but you'll have low debt too.
The truth is, you're not going to get biglaw. If you want biglaw, take the LSAT again and get a 170. That's a lot easier than getting to the top 5-10% of any law school.
Biglaw goes about 10% into the class at either Pepperdine or GSU, FWIW.
And if you want to stay in Ohio (doesn't sound like it), take in-state tuition at OSU or Cincinnati over Case. Maybe even take in-state tuition at Cleveland State over Case. Case is a good school but it is not worth anything close to full price.
