Try Corsair, Performance PC, or EK to buy your parts Corsair I think would have the best prices for shipping but you can always try Amazon. The Issue I see that you might run into is that you have several manufactures and trying to get you LED's on all of them to play nice might be hard. Also since you already need to get your GPU block from EK since the Trinity block is the only one I know that fits that card your best bet is to go with EK or Performance PC and just getting everything at once so you only have to pay shipping one time. Good brands EK, Bitspower, Alpha cool, Corsair. I actually preferer Barrow Fittings because there like $4.00 ea (USD) which is the cheapest I have seen and they make good fittings.
