Presuming you've only began digging into custom water cooling, I'd suggest flexible tubes. Look into EKWB for the CPU blocks, and Swiftech for the other stuff like reservoir and radiator. Both can be found at PCCaseGear.

NOTE: If you aren't doing water cooling right out of the bat, DO NOT boot up the PC without an air cooler! Don't kill the CPU!
