I have the same exact model and had it since 2008 roughly. I do not know anything about computers, let alone The internal components. Planned on recycling this computer and was 30 seconds away from using my Incredible Hulk strength to bust it apart.
Decided to Google how to disassemble the same exact computer and this forum popped up. Not only was it super ridiculously easy to take apart, but I actually enjoyed it as well. Just wanted to commend the author on a job very well done. The pictures along with the locations marked in red made it extremely easy and helpful!!
