Hello,
I am trying to work out if I should go for an internal Reservoir or external Reservoir for water cooled gtx 570 in SLI (two cards). Some of the other specs are, intel sandybrigh i7 2600 quad core 1155, and may be water cooled corsair ram in a coolermaster haf x case. There will be a triple radiator at the top and a dual radiater at the botton with 120mm fans. And do you have any suggestion for a pump.

Would putting the reservoir outside the case cause any issues?
Any thoughts would be appreaciated as I am just starting out to build my first gaming pc.

Thanks
