Without including some of the enthusiast watercooling case manufacturers (Case Labs, especially, but XSPC, Little Devil and Phobya also come to mind), this evaluation is considerably narrowed.
Although I think this air cooling-centric comparison is very useful, some readers might benefit from a mention that boutique case manufacturers offer some very elite cases, usually aimed at watercooling enthusiasts and often very expensive.
When I built my first PC last year, I initially bought a Corsair 800D, only to realize, after considerable research, that much nicer cases were available, constructed from higher quality materials and designed with an older, less blingy, consumer in mind.
Although the difference in performance is not as profound as with gaming headsets vs. high-end headphones, mainstream gaming cases all-to-often remind me of the gaming headset market.

FWIW, I'm very pleased with my LD PC-V8, althoug accessing the case interior should be orders of magnitude easier.
