From a cooling standpoint (and simple physics), the 90 degree turn makes perfect sense... Hot air travels upwards. The only problem is the limited air intake from the bottom of the case...
I still love my Raven RV02 to death, it's by far the best case I've had (even better than the TJ10 I reviewed once), maybe apart from the HDD installation (would've prefered the RV01 version there)..
I'm looking forward to this case, apart from the fact they've seriously reduced fan-numbers both top and bottom.... But I really like the look of the thing (yes I know, I love the Raven series as well, stop hitting me)..

Best Regards
