The only thing I'm not super excited about is the 1TB HDD with only 5400 rpm. I read online that it was relatively easy to replace the HDD (I also found instructions on how to do it in the G7 17 maintenance manual on the Dell website). I was considering replacing it with a SATA 2.5'' 1TB SSD (Crucial MX500, it's 7mm so it should fit).
I'm not too worried about physically replacing the hard drive (although I would welcome any pointers, since this will be the first time that I'm replacing components in a laptop instead of a desktop computer). I actually had a different concern/question: with the order I also got a 3-year plan for premium support and the accidental damage service. I fully understand that any HDD/SDD I replace would not fall under the original warranty, nor the Accidental Damage Service. However, I was wondering: if I open up this laptop and/or replace the HDD, does that void the warranty and/or Accidental Damage Service for the entire laptop? Or just the component that I'd replace? And does it matter if the new SSD is not a Dell product (since they don't exactly sell the cheapest SSDs)?
