Will my set-up work?

I'm tired of my ROARING fans in my case, often getting comments that it is alive and it is keeping people awake in the next room , so I'm thinking of going to water cooling...

Koolance Reservoir & Pump, 1kW Series - Silver
I like the look of this, and it is a very strong pump it seems. I am just afraid of the fact that it says it is louder than other pumps... Can it be adjusted if I want it to pump less L/m? I doubt I will need the full 6L/m because I am a college student and hardly OC, but when summer comes I do a lot of it so... yea


I can't decide between the Black Ice GT Stealth 120, or the Black Ice Xtreme 120 Radiator
Is the extreme any better? I keep reading reviews that the stealth is the best, but the Xtreme is thicker... Also, this might be a dumb question, but is the fan on this inside of this radiator?, am I supposed to add a fan?... I was planning on putting this in the spot that my rear 120mm fan is.


Alphacool XP pro CPU block
I just chose this one because it looked good... I have an AMD, so if there is a "best" one for the money I will switch .

Clear tubing with blue liquid!
30 extra dollars that I don't really need to spend but it will make it look more exciting...


Also I need a good block for my BFG 6800 ultra OC (I know it's old school, but I will build a new PC once I am out of college)

Problems I see. Well, because I am mixing brands, I am afraid that a warranty is going to be voided somewhere. Especially on my pump/res. I am wondering will the fact that I am mixing metals in my system cause a problem? Overall, I'm just wondering will this system cool efficiently, and be pretty quiet without voiding any warranty's.

Edit: I plan on using 3/8 tubing
