I'm not a big fan of neon and leds..just for be clear, the two small green leds of 780 are already too much
Then there aren't windows so..or you keep it open or are useless! Keep it open is an option, because looks so nice!
Regarding the case nothing to say since I really like it! Small, with some good space inside for every components and in aluminum that is always something of premium. imho could be nice if there was a spot on front for a 180 or 200mm fan or some extra air vent without ruin the design of front panel.
I have checked around if someone did some mod or so, but sadly is not so famous and it's a shame; with a 960 or 970 and some i5 can be a very small and good machine. You can put almost everything inside without any issue.
