1. What is the largest drive that will fit size wise? I want to stuff a 500GB one Samsung in there, actually this one to be exact

2. How much does Dell want to change it out?

3. I seem to be getting nowhere with Dell in regards to changing ownership of this device. I have called a few times and I have my receipt/proof of purchase from Amazon stating that I legally purchased it.

Thanks for any help
