I'd probably rock a new case if I where you. If your on a budget you can get the cheap HAF for $40 and mount the radiator on the top of the case with the brackets that come in the XSPC kits. You could mount a triple or a double up there.
I wouldn't do anything but an XSPC kit IMO. The kit will save you money and will make sure you don't forget anything. Get an RX radiator not an RS make sure if you are buying the 750 kit that it has an all black pump/res not a clear pump res. If you have the extra money get the D5 kit.
If you can afford a high end case then get a high end case that will support a thick triple rad on the inside. The new Obsidian 900d comes to mind or a 800d. I have a 800D and I fit a quad rad in the top without modifying the case. The 900D is baller.
So I would go for:RX360 w/ Raystorm CPU Block and 750 Pump/Res for $204
orRX360 w/ Raystorm CPU Block and D5 Pump/Res for $299
andEK WB Universal GPU Block Bridge Edition
Stay away from EK's Nickel products. They will never be able to redeem themselves on that stuff. Even if you NEVER plan on running SLI the bridge addition is the one I would recommend because it comes out from the video card and makes it super easy to just throw some 90s on it and it will look great.Don't forget to purchase 2 90 fittings with rotary function.
That also brings us to fittings. The 1/2" barbs that come with the XSPC kit are GREAT! the hose is CRAP so I would buy some 1/2 x 3/4 hose and you might need new hose clamps for the 3/4 outer diameter. If you want to go with compression fittings I would recommend monsoon because they are cheap and easy to work with (uses a tool instead of blood and pain).
The XSPC barbs are very good though and there is really NO need for compression fittings. They look nice and make it easy to disconnect tubes but they just are not necessarily. If you are not going to buy compression fittings you MUST include a drain line which means you need to buy a T or Y fitting and a plug. Or you could buy 1 set of quick disconnects that are not valved or you can buy a single compression fitting for the tube you will disconnect when you want to drain the system. I don't personally like building in drain tubes so I usually make sure at least 1 compression fitting is in any build I do. Maybe buy 2 90s with compression fittings built in for the video card and that can be your drain point since it would be the lowest point in your loop.
Hope this helps...
Also my reasoning for the universal GPU block is this! For the most part you can not over volt a 600 series card and the same will probably hold true for the 700 series. The cards do not have cooling on the memory from the factory and at least the Asus DirectCUII cards have a separate heat sink on the VRMs that will stay on when you take the factory cooler off. Using a universal block will give you 100% boost 100% of the time. The card will never leave boost mode while you are gaming because it will never get hot. My card stays between 41-48c under full load depending on how much the game stresses the CPU (cpu adds heat to the loop). A full coverage block is a waste of money because it will become worthless when the next series of cards is released. You can move a universal block to your next card and the card after that and so on.
As for the pump... Martin's Lab has reviewed the new 750 and the review is favorable. I have used the old 750s in a lot of builds and still own one to this day. The 750 is quiet has very little heat dump and will last a very long time. There is really NO need for the D5. However if you have a ton of money laying around you can get the D5 it is a monster. Your system will not run cooler with the D5 in fact it may run hotter. It may also be louder as drive bay pump/res combos have a tendency to shake the case pretty hard if they are vibrating.
I'd stick with the 750.
Just my opinion.Edited by givmedew - 2/18/13 at 1:55am
