You'll need a case cracker and a tool specifically to de-energise the CRT: that's the killer part.

Yeah it’s good general advice to always discharge the CRT. Although… the flyback transformer on most of these Macs has a bleeder resistor, so I skip it when I’m lazy now.

A long flat nose screwdriver is actually recommended in Apple's manuals. Just... don't touch the metal part, and maybe consider wearing some insulating gloves.
