I've been following the guide for opening the case and got the bottom grey panel off but now the grey panel where I removed the harddrive from I cant find the first clip. Maybe the guide I am following is wrong, anyone have a picture of which hole I should be in? lol

I believe you need to peel off one of the rubber feet. Under it, there is a hole to access the tab.

The first clips are under the raised bits. Put a screwdriver in the hole and just move it around until it unhooks.
And theres a tab under one of the rubber feet.
