Hard to recommend a delid to most users as:
1) they aren't going to be as keen to destroy a chip without RMA ability (yeah, I realize that OC itself voids warranty, but obviously, delid makes that quite obvious;
2) the process isn't rocket surgery, but you are getting into an advanced process that is really going to scare people off simply because you can brick a $300 CPU in the process...not everyone has cash to burn.
