I actually had a Mac Classic when they were new -- or maybe it was a Plus. That's a very nostalgic picture! I loved that little beige cube.
I remember fitting a little extra cooling fan on top of the case, and some other customisations. It was so magical, the UI, to those of us who cut our eye-teeth on ttys, paper tape, hollerith cards, ADM-5's, oh dear...
Never again in this life will I feel a thrill like playing Fool's Errand on my cube Mac. Actually, I take that back, my first venture into VR was just about as thrilling.
