Thanks for the response guys.

I also decided to try build something arround that rad though at the end i decided in favour of 560 SR1, as more fit to low fan speeds. At one point i also considered X2000, but at the end i choosed obsidian 800d though (and with it seems that rad won't fit whole inside, tubing attachment part will be outside, which is fine by me). Rad length is fscking enormous(605mm!). Pitty that width too (eg. it won't fit without extra work in 5.25 bay area unlike 140mm rads of other vendors). I still haven't got till parts ordering stage, i wish you luck. Gonna be interesting to see how your project will turn out.
I came close to getting the Obsidian 800d. That thing is awesome. But believe it or not, i actually made the radiator fit quite comfortably inside my case. I'm busy with work at the moment, but I'll post pics real soon.

the mother of all rads... that is one LONG rad... dunno how it'll be a "sleeper" if you are going to have 8 fans in push pull in that... IF you get it to fit in the case... good luck!
The front four fans are already installed. As for the pull fans, I'm still waiting for those to be delivered because i didn't think it was possible, but it looks as though its gonna be 7 fans in total. The top pull has no space due to the radiator sitting flush with the optical bays. I'll post pics soon and you'll see what i mean.

Otherwise, this build is looking good. Pics soon guys.
