WC Recommendation

[LeArN2LiVe]

I currently have a Black Coolermaster Praetorian, Dangerden Maze4 CPU cooler and a Swiftech MCW50 GPU cooler. I need recommendations for a 12V pump, radiator, and fans. To keep things cheap and to save space, I also plan to use a fill tube instead of a reservoir. Some of the pictures I've looked at shows the radiator mounted in the back near the rear fan which would also be very sufficient.

So shoot the tips. I'm looking to pay at most $150.00. Thanks!
