Hey Redux,
Sorry for late reply, I don't check this too often. The dive cage only supports 2 drives...I have 4 SSD's in total so I have to mount them somewhere else which wasn't going to work. As for the case fans, I mostly had 4 SP120's at the house already so I thought those would do. Also on the top, only one of the dual 120mm bays is "open" to the chamber with the motherboard. The other one kind of spans the top of the motherboard tray back to the back chamber. This is probably why they have the thin requirements on the rad size. I would actually probably mount your rad on the front of the case in the front chamber (similar to a standard not cube case) then exhaust out the top. Also, with this case my GPU temps skyrocketed without a fan as intake on the bottom (also keep it off carpet).
Overall, I thought this case was a total nightmare to build in...but that's just because of what all I had to fit in it. For someone with 1 SSD + 1 HDD or even 2SSD + 1HDD (you can mount one ssd on the outside of the drive cage...it's weird) it would work well. Especially if it's a full water cooled build. It just wasn't for me in the end and I ended up selling it to a buddy of mine and moving back into my 780T.
If you have any other questions feel free to get back with me and I'll be happy to answer them!
