Hey dude since you have dual slots try these people out.
http://www.swiftnets.com , take a look at the MCW2001. The kits come as shown in the picture, looks like nice insulation to me, anyhow, they are a little expensive for each complete waterblock/pelt then other companys :-(. Also if I were you I would stay away from submerged pumps, if you got the room just get an external pump like a mag drive 250 and a 4x4x4 resivor it cheaper too
