Water cooling, should i?

Hi, I was thinking of having my system water cooler because it seems like the best option for these reasons.

1, Your system runs cooler and quieter
2, You get extra performance from overclocks
3, They look nice

But I havent a clue what i'm doing as i've never looked into water cooling, i'am preety pc able however I did build my pc all together myself, did take the cooler off my gpu to apply as5 etc and I have overclocked them.

I was wondering is it easy to do and what risk are involed, I was looking on the ocuk site and these water coolers look amazing and so easy to do.

As you can see the Zalman caught my eye, water coolers cool the gpu/northbridge and cpu right? thats all thats needed?
And what If I upgrade my pc, do Zalman bring out different water block for different gpu's/cpu's etc even say 5 years down the line if I keep this water cooler by then?
And my mate told me theres a chance of leakage and you have to change the water, surely leakage can be avoided if I do it right? how often do you change the water? any other things I should be worried about?

Do not buy the reserator, it's like a tt bigwater, an insult to watercooling.

If you want a kit at least get a siftech apex ultra and either a maze 4 or mcw55/60 gpu block.

Specs would help also.

That means nothing to me, if it runs the cpu/gpu cool when overclocked - and is completly silent and looks great how can it be bad?

ATM i'm only on a barton 2500@3200, leadtek 6800gt, abit nf7s v2, but if i were to buy one I would want it to look nice and last years and years, i assume you just buy different gpu/cpu/chipset blocks when new cpu's/gpu's/mobo's come out?

:/ I would like something both silent and runs very cool :/, any recommendations and prices? the cheaper the better obviously.
