This thought crossed my mind because there's an used G3 B/W on its way to me right now:
As a long-time PC user recently converted, I'm wondering if someone could jam a Windows machine and a Mac machine into a single box. What I'm thinking (well, that's a theoretical thing. I'm not sure I'm ready to gut both my desktops to try this) is that one could create a plexiglass case, into which he could mount the motherboards, cpus, harddrives, etc by creating whatever kind of mounting devices might be necessary. Put the PCI cards and the drives in two (I'm thinking about mounting the systems side by side, like they were two desktops sitting next to each other). Now, here's the hard part: of course, it would be a pain to have two moniters, keyboards, mice, etc. I know they make switchers for moniters, but would it be possible to install toggle switches on top of the case that could control the moniters and USB ports? (It seems like attaching a cable to the pci video output inside the case and then wiring it to the switch would work for the moniter, but what about USB, sound in/out, etc?). Basically, could there be single jacks in the back of the box for pretty much everything (dual power sources, of course), but with switches that could pop the control from Win to Mac and back?
I know I've kind of lost it here, but nice thing is that you can dismiss me as a nut and not respond. Thanks!
