Not mentioned in the guide is that you have to remove the IR sitting in back of the front Apple logo before you can remove the motherboard
Flip over motherboard, gently remove 4 x Torx 8 heatsink screws on the bottom (not the big Phillips screws on the top). Please note : Warranty is void with this step.

Apple Mac Mini RAM Replacement procedure
Remove Bottom Cover
Place your thumbs in the depressions cut into the bottom cover.
Rotate the bottom cover counter-clockwise until the white dot painted on the bottom cover is aligned with the ring inscribed on the outer case. You do not need to apply much downward pressure while turning.
Tilt the mini enough to allow the bottom cover to fall away from the outer case.
Remove the bottom cover and set it aside.
Replace RAM
Release the tabs on each side of the RAM chip by simultaneously pushing each tab away from the chip.
These tabs lock the chip in place and releasing them will cause the chip to "pop" up. After the RAM chip has popped up, pull it straight out of its socket. Repeat this process if a second RAM chip is installed.
