Im running out of room in my case for my rads and stuff and i had an idea to put it all in an old pc case i have but im not sure how that will affect flow with my D5. The case would be under my desk and my computer is on top of the desk , the highest point in the system would be about 4 feet above the lowest point and im wondering if where i place the pump would make a difference in flow. Should i put it at the bottom or in my main case ? there will be about 10-11 feet of 1/2 inch tubing total in the system. And has anyone ever tried this ?
