WC Maintenance

What kind of maintenance does water cooling require? If its setup right can I just leave it or am i going to have to check it out pretty often? I'm thinking of using it in my HTPC since its enclosed in a cabinet.

Well, you should take it apart and clean out everything once a year or so. Also may want to replace the tubing when you do that if it has any kind of film on the inside.

Other than that I would check the water level couple times a week for a week or two once its setup, then if there is not much water loss then check every few weeks.

Sounds good, im probably going to go the WC way then.
