i have enough room for either, but i would prefer a dual, due to less refilling and lack of a 5 1/4 bay cover (shouldve kept that ) but would it kill me to get a dual? or is single the way to go...
A bay-res looks good, especially with LEDs, but doesn't work very well as a reservoir. They're a serious pain in the ass to fill and don't bleed the air out of the system as well as a tank-style res.
When I mentioned bleeding the air out, I didn't mean filling or draining the reservoir. Bleeding refers to getting all of the air out of the cooling loop.
Single bay res don't trap air that well. Even the ones with center-dividers are prone to sucking circulating bubbles back into the loop. Any air in your loop (especially any that gets trapped in the radiator) hurts your cooling. Dual bayres don't suffer from this as much.
