Ive just sold my v354 but it might be possible, definately possible to fit a rad in the front, and it will be possible in the top but you might need to use a slim fan on the top rad, depends on your motherboard and its +12v socket placement. Ive seen someone with a rampage iii gene mount a h50 with fan in the top but they had to heavily modify the fan for it to clear heatsinks etc, i tried it with my maximus iii gene but it was a no go as the power lead got in the way.
