Compatibility?

Right i am a newb to watercooling and learning as i go along, i want to start buying some water cooling parts cause i dont have enough cash to jus go out and buy it all at once....so what i want to know is can you buy different pieces from different manafacturers and they will still all fit together??

thanks

Is this any good and would i be able to at a later stage use it for cooling the gfx card aswell?

or could anyone reccomend a complete system so that i dont have to worry if i get the wrong part, nothing top of the line but i figuer if i'm gonna spend money it might as well be worth it..

or even this one?

The Thermaltake it is money down the toilet the second one looks nice but you need to google for it.
In order for you WC to be upgradeable you need to make sure that the barbs are same size ie. 3/8", 1/2", the pump can support another block and the radiator can take the extra heat. I would suggest you check this out: www.alphacool.com and compare prices with UK stores. Make sure you read all WC stickies and especially the recommended parts sticky.

Thanks, like i said i am learning as I go along..i read up as much about it as i can and will continue to do so..cheers

Yeah i agree with flip. Don't waste your money on that thing
