Looking to watercool my X1900 cards and for the moment my CPU too but not sure which makes are the best ones to go for. Ideally looking for performance and as queit as possible. Budget around £200-250 (will be aiming to get 2nd hand kit where i can). Must outperform a sycthe ninja and good (but very loud) air system. Will be custom building my own case too so size, etc isnt important as i can work around it.
