Here is a quick pic i drew up of what i'm working with. I have a lucite(plexiglass) box i i'm going to construct as soon as i cut the hole for my fans in it. I have a Chosen Atman 306 500gph pump that is submersible but doesn't have an intake valve so i plan on epoxying its intake to the bottom of the res. and drilling a hole for the water be drawn through so it is a tight fit with the pump intake and lucite bottom of the res. Then i have my pump going directly into my heatercore which has to extended copper pipes out of it. I have two Vantec Stealth 120mm fans i will be putting on one side of the radiator with a shroud to pull air through or push through haven't decidied yet. Then just two tubes leaving my box going to my computer which will be sitting right next to the box or even ontop of it. Critique please
