hi mate.
i have a hades. it is very good for cooling.
but i have seen good reviews about the 690ii advanced as well.
its really personal preference.
my old case was a generic store case and the hades dropped my temps by loads.
also be aware that you get the 2 x 200 intake fans, and 1x 140mm top fan and 1 x 120 back fan.
you dont get the other 140mm fan for the top even though there is 2 slots for them.
also the fan controller is complicated to wire up (well it was for me)
but i must say, i am very happy with the case.
also with usb ports etc.. at top of case, this is fine beneath a pc desk. but if you are placing on top of desk, this will mean standing to access this.
but the hades is a solid case with loads of room inside and i have not found any faults with mine yet, and i have had it 6 mths
