well the one thing i didn't take in mind when looking for into watercooling was the noise.. i knew it will be low but that wasn't my first concern.. the pump is very silent.. unless i put my head on the case i dont hear a thing.. but i didn't take it into account my PC will sound (when i try..) like an aquarium

first run was funny as hell!! there is a fan speed controller for the 120 fan on the rad.. unless its at top rpm (no need really..) its completely silent as well.
as for the price.. as i said before the taxes here suuuuuuucks.. but i found this kit at 2 places one near me and one very far away (4 hours drive..) and since i dont have to much free time (and fuel would cost.. well..) i bought it in the place near me.. the far away store offered it at 67.56 GBP (cheap!! i couldn't belive it.. as prices abroad seemed the same!) the place near me asked for 86.11 GBP and i got him down in 10 sec into 73.82 GBP.. said ah.. i dont have time to look.. he was a nice chap.. i said what the hell.. got the kit 2 days later..
as for the UV the pipes are UV sensitive too.. (and i could see it even under the light.. but since i dont have an lights other then the led in the water block\pump.. i cant really tell.. maybe i'll do some case moding later who knows..
as for the PC starting without the pump working... i'm not sure..

i'll find out..
as for now.. i'm pretty happy with it..
*and i'll say it again.. i had SO MUCH fun putting it together!!
edit-

if you look closely in this pic.. you could see the UV liquid glowing in the water block.. so i guess it works and i just need to add some led for the pipes to glow..
