Hi I'm wondering if I could fit a Corsair H100i V2 into a define r4 to cool my 4790k. The motherboard that I've is the MSI z97 G43 with 16 GB (4x4gb) corsair vengeance LP RAM.
It should fit.
Though i'd recommend to look at kits from
Swiftech: http://www.swiftech.com/H220-X.aspx
Alphacool: http://www.alphacool.com/alphacool/de-eisbaer

Much higher quality and features compared to the crap made by asetek for Corsair, NZXT, Arctic and many others.

280mm radiator won't fit without modding as the fans will hit the RAM modules, some people have gotten it into the front near the HDD bay with some modding. A 240mm radiator will fit in the top though as the fans will clear the RAM (Just).
