Hiya,

I called Applecare twice and asked two different people who both put me on
hold to ask senior technicians if ME opening the case would void my
warranty, and both times I was told no, it would not void the warranty if I
took the case off.  The second guy said that although going into the case
itself would not void my warranty, if I damaged anything in the process the
warranty obviously would not cover damage that I did.
If anyone can show me something from Apple in writing that says that opening
the case will definitely void my warranty I'd really appreciate it, because
I am on my way to the hardware store to get the tools.
  
Thanks,
Maizy
