Just upgraded to a BFG GTX 280 OC (excellent deal on OcUK) and as I couldn't be bothered with the hassle and expense of a GPU waterblock I have made my water loop CPU only and seeing some great temperatures because of it.
It's not as attractive as my last setup, but I still like it. Took me a while to figure out whether I wanted to keep the radiator internally and where to mount the pump/res, but I finally made my mind up and got it all put together.
Cables will be tidied in due course, I just had to get everything together asap to get playing some games
