I need to know how much extra time to allow for water-cooling, if I already know how much time it takes to build an air-cooled, non-overclocked system. 
I've been hesitating to start my next build because I'm worried about how long it will take. There are times when I get very busy with my work or I have to be out of town for a full week at a time, sometimes more than that. What worries me is that I would buy all these parts, but weeks or even months pass before I can build up my system, and something faster/better/cheaper will come along.
I've done a bunch of builds on air-cooled systems so I know that drill pretty well.
In 3-4 hours, I can go from an empty case to having Windows installed. But with a water-cooled system, how much extra time do I need, especially on my first build?

My plan is to w/c the CPU, and GPU, but probably not a full-cover block, so I would need to air-cool other parts of the vid card. I would also need to somehow air-cool the chipset and maybe the RAM, or so I've been told. I'm thinking that I would do a single loop with a 3x120 radiator, a 655-type pump (maybe with custom top), and a separate res, probably using compression fittings rather than barbs or clamps. I'm planning to use my existing Corsair 700D case, but remove the existing motherboard/CPU/RAM.
Over-clocking would come later, after I know that I have a solid loop and I have a system that I can use to get my work done. I know that some guys spend days just to tweak their system to get the highest possible overclock. I may do that also, but the first priority is getting that system up and running.
Thanks guys.
