........... I've had my Fractal for a couple of days now - nice looking case, but I have to say I am not blown away by it.
I think, if you are going to fill the case, lots of the benefits are compromised - it will hold (in my setup) multiple 5xxx GPUs and 5 HDDs - but not silently or coolly. There are also a couple of design niggles (to my way of thinking) such as the extra inner doors covering the front intake fans, the raised seam which runs the full height of the case between back of mobo & behind HDD racks that prevents cables being run between the two areas ..... nothing serious, but an irritation.
However, the FD fans are pretty good - shifting good amounts of air quietly.
All in all - I don't think it is quite as good as my Antec 902 apart from the HDD bays which, although side on & therefore presenting more of an obstacle to the flow of air, are easy to use & look good.
