Disassembly Notes
The top shell must be tiled up when pulled all the way forward to release.
Watch out for the speaker on the left side when sliding the shell
The top rear screw tab may catch on the PSU and cable (lift rear when sliding avoid)
PSU slides into tabs in bottom shell
When connecting the PSU back to the system the mother board power connectors should have the black wires next to each other.
