Hey guys, Looking to finally watercool my pc (cpu + gfx). As it will be my first time, Im after some advice.

Current setup :

I7 920 @ 4ghz
6GB Ram
Gigabyte 780 GTX x 1

Now i do have a corsair 800d which i know will help with space , i have no idea what im looking for at all so any help would be great, looking to get everything as cool as possible and quite quiet , sounds like an aircraft at the moment with 8 apache fans .

budget around £400 , im sure it can be done for that

Edit : would like to also note, i may add another GTX in future, so would like to have the option if needed

thanks again

thanks for the info, the 480 rad means i may have to cut the case to fit, may go for 360 and possibly add another rad in the bottom, that way i only remove the HDD bottom bay., many thanks for the advice
