The Ninja had everything going for it: silence, performance, a low price, and, er, size. It's monolithic design was a concern, in that people really did need to be concerned that it might not fit in their computers. The Ninja Mini is less of a revision and more of a derivation: a much shorter, broader heatsink that's got titanic shoes to fill. Besides a simpler mounting system, lighter weight, and improved compatibility, has anything changed? That is to say, does it still perform (to continue the mixed metaphor) like a chainsaw at a water park?
