Well, are you guys sure you're looking at the "It's me or them" thing the right way? I mean, it's not that anyone would stop you from owning your property, but it's if you spend more time on Aminet than talking to her, no wonder she'd be pi$$ed.
Having said that, maybe I'm just very lucky - I have 4 towers under my desk (will possibly be 5 when the X1000 arrives), plus another two A1200s. The girlfriend really doesn't have any interest in them at all, but she's perfectly happy to let me work away

Back on topic, years ago (Christ, about 13 years now!) I was using an A600 as the basis for a room automation system and managed to pass mains electricity (230V) through the shielding and ground plane. Needless to say I feared the worst, but turned it off and on again (after fixing the bad wiring!) and it was fine! Still works to this day!
