Actually, I don't know if there is a place with formal instructions but the hardest part of the upgrade for me was finding the pressure points on the case once the screws were removed to get inside. I sort of removed the screws and grabbed a butter knife and screwdriver to pry the case apart. I believe (if I remember correctly) there were two pressure points on either side of the case to remove the case.

Once you get the case open just remove the hard drive I can't give you exact instruction but it really was not that difficult to figure out.

Next you simply put in your new drive (I used a 120gig) reassemble and turn on. Put in your cd that came with the unit and it'll ask you something along the lines of "restore as new?", select that and it'll set up the operating system.

It is definately not like a replay where you need special instructions or a special patch. It is very very simple.

I still haven't had any *real* problems.
