These two are the same thing just at two different places. 4 cents more at Sidewinder...
That would be fine for just your CPU.
If you do decide to get that, you should get new tubing, as the stock tubing that comes in the kit is not very good. The kit comes with barbs for 1/2"ID tubing, so you should get 7/16"ID tubing. ( Having the slightly smaller tubing over the bigger barbs will create a better seal. If you do that you also do not need
barbs, but you could use them to be safe. Two more things you should get are distilled water and PT_nuke or a silver killcoil. Ther PT_nuke and the killcoil prevent things from growing in your loop. You will have to decide which one you want. They are both just as good. With the killcoil, you will have to just drop it in the reservoir/pump, but you should bend it in a way that it doesn't get sucked into the pump causing it to die on you.
If you go with the PT_nuke, you will have to just put a few drops in the water. ( 2-3 should be plenty. ) ( Too much PT_nuke will cause the water to cloud up on you. )

EDIT : About the tubing... I would highly recommend Primochill tubing.
EDIT AGAIN : Oh, forgot about fans...
You will probably want to get new fans. With the RS series rad, you will want a fan with high static pressure due to the high fins per inch. What would you noise tolerence be? You might want to keep the stock fans if you only want to spen so much money now.Edited by Triangle - 8/1/11 at 9:58pm
