How leak proof are WC connectors? I was planing a loop that will be a pain to access.

Depends on what you go with. The vast majority are fine. In your case, I'd recommend the tried-and-true worm drive clamps I've always used. They are cheap and do as good of a job keeping tubing sealed as you can get.

As far as the barbs, they are also fine and should last indefinitely within reason; I'd tear down at the one year mark for cleaning and checking connections though. Most fittings come with a recessed o-ring now-a-days. Just put them on and crank them down. If you have ones without a recessed o-ring, just make sure there isn't any bulging and leak test, leak test, leak test. (Get the ones with a recessed o-ring. )

I plan on never cleaning this I plan on a glycol based coolant. If I can get the wife to let me do more home mods that is. I want some geo cooling in the summer and a loop I can switch to internal for the winter for heat I have been planning this for a long time and think I can do it for about a grand for the first rig and a couple hundred for each other rig. It is just neat and I want to do it.

In that case, I'd use real plumbing fittings for a closed external geo loop, and use a heat exchanger (or exchangers) to interface with your also-closed computer loop(s).
