Building rad outside case

Hi,

I couldnt find any review sites of temp differences with watercooling between inside and outside the case. What is the best option? PC will be in a confined area in the corner of the room.

Doesn't make a lot of difference. Think about it; most of the heat you were generating is now in the radiator. So long as the air going through the radiator leaves the case, the case air remains near ambient. In some small way, the separation between the radiator exhaust and the case intake helps keep the hot air away from the cool air. With a radiator outside the case (especially in a confined area) the exhausted air can be re-circulated back through the radiator reducing the rad's efficiency.

Thats what I was thinking, but the problem I was having with that idea was I couldnt find a decent case that created such seperation from front to back, as majority of cases have the front hard drive bays blocking the front fan. Ones that do are absolutely massive cases that cost a bomb. For some reason in my head I was thinking a case that had a front intake which would create a wind tunnel effect through the back pulling it out?? What parts would you recommend I need for a system that contains an I7 920, GTX 295 Dual PCB? Triple rads? Double rads? Single rad or 2 units of rad?

<pompous>My apologies, I don't do specs. I believe it's in your long-term interest to find out for yourself and then ask for criticism. Look into the water-cooling section here, find a block, look at gpu blocks, see how incredibly expensive they are and re-think the whole thing, find the money, do it anyway</pompous>

i have a 360 on the extrenal off my case and works great for me as my GPU's are air cooled case in question is a RV01 look it up very good case for cooling

Sorry for the delay in reply have been busy. Ive alrready got a GPU block and a cpu HK Heatkiller rev3.0 block. What I am stuck between whether I need a new case or not, or build outside and how much cooling power I need? 1 rad or 2? As this mmight mean a change in case. If being watercooled do I need to worry about getting the best air flow inside the case like antec 1200?
