I came across this case mod. I’m not usually into case mods, seems like too much work. But my Powerbook died the same death as this guy’s and he brought it back. I might need a second desktop in the future so this is sounding like a real option to me.  I think I would make mine look more like a Mac Mini rather than perforated metal sides. I guess it would be a Mac Maxi or something. :) I like the cheap acrylic case. That’s pretty neat.
