wow...i like those....thoughts:
both B and C draw my attention away from the CPU and PSU.....in both of my attention is drawn to the Vidcard, HDD/Optical drive cages, and the bottom of the Duct.
both D and E are very clean and very nice, both designs seem to accent not one or teo particular areas of the case, but my attention smoothly traverses the entirety of the case.
A, however, is my favorite....it accents the CPU, PSU, HDD'Optical drive Cages, and Vidcard. It does cover up alot of the inside, however. For me, the design of A seems to reflect a confusion of sorts. The designs seems enigmatic, like a maze...it seems to ahve a little bit of abstractness to it.
