I have 2 B&Ws in use, one with a G4-450. Both are very nice machines. I remember looking at them back in early 2001 when I decided to buy a 8500 powermac and beef it up with a G3-400 and tons of RAM (B&Ws were real pricey back then).

Nothing realy bad to say about them, and the PS seem to be much better then the early to middle G4 designs with ADC.
