So my hard drive crashed on my iMac last week. And for Apple to install a new 160G drive it would cost me $185 plus $85 labor.

Anyone know the best source for a much bigger hard drive on the cheap?

Is this something I can install myself?

i can't offer any recs, but they are pretty easy to install. just a matter of removing the back and popping out the old, and in with the new

Plenty of youtube tutorials for a zillion different models.
