I used this guide in conjunction with this video for reference that was really helpful: http://www.youtube.com/watch?v=ShY8zuT-w... (and part 2). Repair went really easy (just take it slow). Hardest part for me was pulling out the screen. The torx screws are pretty far in and the 26 piece kit I bought from here wasn't long enough to reach (the extension has a large round magnet on it that will not insert far enough because of limited space). Thankfully I had a torx at home that was longer for that specific size, so I was able to unscrew just enough with MY torx and use the magnetic one to grab the screw (absolutely necessary to have a magnetic version). Bought the Western Digital drive and found out that it would not format with the original OS Tiger disk. Only OS Snow Leopard's Disk Utility would read the HD properly and format for Mac. If buying the Western Digital, make sure you have a newer OS to install than Tiger. I read about possible problems with OS Leopard's Disk Utility and WD drives as well, but I cannot speak specifically for that.
