My hd failed and i used this guide to replace it with the same model. The problem i'm stuck with now is installing os x again. The installation starts and goes on for a while, while the hard drive makes a weird clicking noise. Then randomly the installation fails and asks to try again. I've done this ten times now.
I'm not here to rant though, i've some useful tips as well.
Instead of buying suction cups, i used a vacuum cleaner inserted into the back of a plastic container to create more pressure per inch. Also used duct tape on edges of the container to create more friction and not damage the glass. Although later i noticed you could wedge the sharp edge of a knife between the glass and the case and widen the gap with a fingernail, then pull the glass out completely.
A note when you're buying screw drivers... The ones with the interchangeable bits won't reach the screws on the lcd, so be prepared to fiddle with strips of paper and screws falling into the sides!
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
