Problem 1- crappy lucite tops crack when barbs screwed on too tight or with too much teflon tape- very VERY slow leak around barb resulting in me trashing the stupid cheapo block.
Problem 2- Bayres leaked very slowly, in fact, so slowly that I only caught it 2 weeks after it started (at least I think 2 weeks judging based on how much it was leaking and how much had leaked already). The water and antifreeze leaked down the IDE cables into the two HDDs, corroding and eventually bridging some of the pins. I was wondering why one of my hdd's stopped working, then the other one stopped a day later. Took the plugs off, scrapped the crappy bay res, made a nice PVC res, cleaned the pins and cables with baking soda and water, 'puter putters along flawlessly.
