Thank you!
This guide works well for the 4320s as well, though there are a few small differences.
The battery compartment has 4 screws and there are none on the back.
The keyboard is held by 4 screws.
The touchpad has the same type of connector as the keyboard.
The hard drive cage is held by a #1 Philips and two #0 Philips instead of #1.
