I swear if you can't do this slowly and carefully in 10 minutes there is something wrong. Removing the playfield is even faster and simplier. Removing flipper button assemblies simple. PC unit too easy. Everything I have attempted to remove is easy except for say the monitor itself. That takes a little bit of maneouvering and care.
