My housemate had an Amiga 1000. Cool computer for the time and we played many a video game on it. One day the floppy drive died. We bought a compatible floppy drive and opened it up. There was a aluminum shield over the drive and most the components that required a large number of screws to remove. I've had easier times opening up a laptop to fix something than that pain in ass 1000...
Commodore took radio shielding rather seriously back then. The wedge Amigas (A500, A600 and A1200) also had excessive metal shielding everywhere. A lot of Amiga owners nowadays just dispose of that as it always gets in the way when you have to fix the next thing that breaks in these machines.
