Back in about 2000 I managed to get my hands on twelve free NeXTcubes that a tech company was throwing out. I was over eager with my generosity handing them out to the local geek community, and before I realized what I'd done, I didn't have one left for myself. Always regretted that, as they're very cool machines even just sitting on the shelf.
I do still have stacks of NeXTStep CDs sitting in a closet though. I used one of the Intel version ones a couple years ago to install a copy on VirtualBox like this guide is showing. Fun to screw around with it, brought back fond memories of my days in school using an original NeXTstation.
I let a NeXT cube through my hands too, and regret it as well. In high school I guess I was the teacher's pet in my electronics class, and we regularly got old computers and parts as donations. I helped the teacher get a classroom's worth of PCs up and running as a network so he let me have the oddball donated NeXT cube that was just gathering dust. Then in college I traded it to another geek for an Xbox and a bunch of games. Seemed like an even enough trade at the time although now I wouldn't mind having that lovely magnesium cube around.
