For those of you who make your living (or part of it) building computers: do you, or would you offer liquid/water cooled computers? Would you warranty the system? What kinds of WC setups would you be comfortable shipping and trusting the customer with? Is it worth the potential for customers majorly screwing up their system? What kind of instructions would you include for the customer? I've not even water cooled a system for years now and I'm not sure what products are out there and whether or not it's worth the money and time investment to test some out and determine whether or not liquid cooling is a viable option; my rigs come with a standard 3-year warranty, upgradeable to five years, and I wouldn't want to have to knock that down.
