Remove the top shell, flip it over, and place next to lower shell
The two halves are connected together via the cooling fan wire. BE GENTLE when separating them
In typical Microsoft fashion, they've made it complicated to remove the fan wire. Not only is it wedged between two transistors it's also adhered with an epoxy like substance.
Using a craft knife, carefully cut through the epoxy to get the cable free. Work slowly and carefully. The thick substance and awkward angles make this a slightly tedious process
Be VERY CAREFUL. You can easily cut the cable here accidentally. If you cut your red/black wires you'll have to patch them. "Slow is smooth, smooth is fast"

Tape will need to be replaced during reassembly. Electrical or kaptom tape will suffice
Take note of the amount of filth collected on this fan. Inadequate cooling could kill your supply, or worse, become a fire hazard

The fans +/- wires are covered by a thin protective sleeve.
Apply some electrical or kaptom tape to patch it if necessary.
Initially I tried to use shrink tubing here but the smallest diameter I could get around the plug was a 3/8" tube which will not properly seal around the cable when heated
If you accidentally cut through the entire cable (+/- wires) you'll have to resolder them together and cover with shrink tubing.
