re: Hot tip
So, the second hard drive replaces the CD drive. To get to that, all I had to do was take out the battery, remove 2 screws to get the bottom cover off, then remove one screw to take out the CD drive. It was that simple. I've also taken it apart to replace the thermal paste and while that was more complicated, Dell actually provides step-by-step instructions to disassemble the laptop that far. These kind of laptops are seriously quite nice in terms of repairability.
