after looking at both review... the design may seem odd... but actually it function really well.. ecspecially in cooling department... most of the reviews stated that fortress 2 fares better in cooling performance compared to raven 2... but that was when fortress 2 is equipped with ap181 fans... while raven 2 not.. but raven 2 evolution does come with same ap181 fans as fortress 2.. so i think cooling performance will be equal for both... or fortress 2 still cool better?
Man, go with either, you CANNOT miss. So decide based on price and looks.
Personally, I own a silver fortress and I can't think of a better looking case, but tastes differ.
Keep in mind that they cool very well on air, but due to their layout installing a water cooling loop may be troublesome. I'm currently water cooling 2 GPUs and the CPU, but this required some minor modding- the HDD bay needs to go if you want some decent rad space. The SSD fits easily on the back of the mobo tray, the HDD... Well, I'm sure it's less than happy with the undignified position it's in now.
All in all, they're both good for air and require some fiddling for liquid.
I'm really feeling that Silverstone. if I didn't already have a case I might be declined to run out and get that. I considered the Raven 2 RV02-EW and I still might do a build with one later on down the road.
