Alrighty, you won't be able to use that Corsair AIO because of the way they have connected things - basically sell it and with that money buy the other components.
First off you need the following:
cpu/gpu water blocks
You can go to this page: http://www.frozencpu.com/cat/l1/g30/Liq ... d=6cjoTMJR
and basically pick out everything you wanted from there. I would personally recommend 5/8 x 3/4 Compression fittings (remember to pick out 5/8 x 3/4 tubing to fit it) but most everything else is basically user preference. Here are a couple of tips in water cooling itself to help you get started:
1) No matter how you connect everything together, always connect the reservoir outlet (water going out of reservoir) directly into the pump inlet. These will be marked specifically on the reservoir/pump so there is no guess work. Just very important that the reservoir feeds the pump directly.
2) How much radiator space do you need? Rule of thumb is that you need 1 x 120mm radiator per block in your loop + 1. so if you are putting a CPU block and a GPU block on, the bare minimum would be 2 x 120mm + 1 x 120mm for a total of 3x 120mm radiator space. This is bare min - there is nothing wrong with going more.
3) Because water distributes temperature to its entire volume evenly, there is no special order everything needs to be in. The ONLY thing that matters is that your reservoir feeds your pump directly.
4) When you have everything hooked up, you must do a leak test. Basically disconnect the PSU FROM EVERYTHING and just have your pump connected to the psu. KEEP IN MIND THAT YOUR FIRST ATTEMPT WILL NEVER LOOK GREAT. Get one of these (http://www.frozencpu.com/products/5141/ ... ector.html
) to turn on your PSU without the motherboard.
5) Turn on PSU that is ONLY connected to your pump once you have filled the reservoir. The reservoir will slowly drain - so keep refilling it until you see water coming in from the loop and it can fill itself. There WILL be air bubbles - just a matter of moving around the system a bit to get rid of air bubbles, and time. Turning off the pump and turning it back on also helps eliminate air bubbles. **NEVER RUN YOUR PUMP WITHOUT WATER IN IT*
6) Leave the leak test running overnight, with paper towels at all the connections. Check the next day to see if there are any leaks - hopefully if not you are all set to hook everything back up and get your system going.
