I installed a WC kit on my PC about a year and a half ago, I consider myself to be an "advanced" PC user and know my way around the insides of a PC quite well and have no trouble with installing/uninstalling hardware, However at the time installing that WC kit was more painful than a trip to the dentist. When the pump died on that kit I switched back to air, that resulted in a slight increase in temps and a HUGE increase in noise, but I accepted that change due to ease of install and temp difference wasn't that much.
