It's raining modules! The I/O board, video card, and power supply all come out from the same side of the case.

We stop for a moment to admire all the numbers indicating the order of operations. Labels are great for repairability! (Believe it or not, not everyone reads the repair manual.)

The power supply is the last easily-removable module to come out. It's held in place with a single T8 Torx screw.
