Creating a customized DOY water unit, would be really fun. But it is so difficult to easily procure the parts (water blocks, tubing, clamping, reservoirs, clamps) on the fly -- and am not talking about harvested parts from a/c's, pumps, refrigeration units. I would still prefer to buy a company made liquid cooled kit. Though, Rohan, if you could give a summary of how you assembled your kit, it would be nice. Or is it proprietary to your office. If the parts are readily available, and I can go back to shops and choose what I want, then creating a simple blue print, and implementing it should not be that difficult.
Regarding the price / performance ratio vs. a standard HSF, I see it as a good benefit, if I want to keep my chip always on highest possible OC. Some things are done just for 'kicks' sake. Liquid cooling would fall in that. Also as Madnav mentioned, it could be worth while, if the kit is reused for different sockets. (Though there could be an issue for the back plate and water block compatibility). I am swaying towards the 'Swiftech Apex Ultima'. Lets see what else this great discussion brings up.
i like the compact one!
