When I run my 360 rad off the top the tube returning to the pump goes across the top of the mobo so its nearly out of sight. I used a 90* off the rear where yours is a straight. I had to cut one corner of the fan off with a hack saw to make it fit nice but it cleans up a bit of tubing. I'm of the opinion that less is more too. I reckon you could just run the loop through the Vreg's 1st then the cpu? You could still use both rads in a loop like that i suppose. I kinda thought a guy would run the water through the coolest stuff 1st and then the hottest?
