Heater core or real rad?

Okay, here are a couple thoughts on mounting, keeping the same old case and forgoing the left side window. :( Any thoughts on my two versions of mounting the 2 x 120mm fans and rad/shroud onto the side of the case? I'd use some reinforcement on the inside of the door, and my entire case is lined with relatively ineffective but expensive Akasa Paxmate.

My thinking on the second one is to use the draw of the 2 x 120mm to pull air in through a filter in the front, past the drives, and save on noise by pulling those fans altogether. Blowhole, rear 80mm and PSU fans stay as-is.

It is best to have cool air pulling into the rad for the best temps since the air coming in is barely warm.
