[Rathji]

Mrs Rathji recently started using my PC for work stuff and she is complaining about the noise the fans are making. My preliminary inspection indicates that both GPU and case fans are making a slight amount of noise, so I thought water cooling might be a good option. Problem is, I know next to nothing about these things, other than the idea of water + computer seems pretty strange.

Can I eliminate fans entirely?

What should I be looking for in such a purchase? Certain brands? Are there different types?

I will likely upgrade the case at the same time, do I need a specific type of case, or will any random case work?

I am planning on upgrading my mobo/processor/RAM later this summer, I assume it will be compatible? Safe to assume I would need a new heat sink for new processor? Moving from a Q6600 to an i7 most likely.

Same question about video card, is it safe to assume that an upgrade to the card would require a change in the heatsink?

How about the size and 'hose' configuration, will it get in the way of SLI/Crossfire? Not sure if I will go that route, but don't want to lock myself into something that ends up limiting my choice.

My final question, and likely the most important one, is it worth it? financially or time-wise? I have always viewed water cooling as a overclocker's realm, and that is normally something I really don't care too much about, but that's partially due to the fact that I have never had the funds to put into a high end PC.
