Here's my suggestions:
Pump: Swiftech MCP655
CPU water block: Swiftech Storm (revision 2)
Radiator: DangerDen BlackIce Extreme III
Swiftech Rad Box. To secure the radiator in place. Pick a color.
Tubing: PrimoFlex 1/2" inch inner diameter, 3/4" outer diameter tubing. At least order 20 feet of this tubing to make sure you have enough and for future upgrades.
As for your reservoir, I suggest you use the T-split since it's simple cheap and easy to implement. Here's what you need.
T-splitter 1/2" inner diameter tubing from Frozencpu.com.
Fill port: Danger Den 1/2" inner diameter fill port and cap.
And to secure the tubings you can use zip ties/ cable ties. You can use some 3/4" inner diameter reusable tubing clamps but they are pain to take off. I recommend ties for easy installation and removal with clippers.
Coolant. I suggest you use them non-electrical conductive coolants to protect your system in case of leaks and accidents. It's thermal properties is not as good as the car coolant/distilled water mixture and the difference is about 1-2 degrees celcius but it's worth it with it's non-electrical conductive properties.
Non-electrical conductive coolants:
Fluid XP+ High Performance Non-Conductive 32 oz. Liquid Cooling Fluid
Innovatek Protect 1 Liter Non-Conductive Water Cooling Fluid
PrimoChill ICE Non-Conductive Liquid Cooling Fluid (32 oz.)
If you don't want to spend the extra money on there coolants then here's the Anti-Freeze coolant and Distilled Water concoction.
Car antifreeze is needed to inhibit the growth of microbs and or fungi in the water. You can get this at your local car shop like Autorzone or PepBoys or the one in your garage or trunk. Choose your color.
And lastly water. Distilled is recommended since it's pure and does not contain other contaminants. Used good quality water like Dasani and Aquafina and not the one in a regular 1 gallon container you find in your local 7/11 store.
There you go, that's what I would recommend to you. Feel free to ask me if you need to. Also check out my video below for my water cooling setup.
