yup, lowest point possible. my initial idea was to have it open down to the bottom of the case. but i didn't want to drain the rads when i open the drain since my initial need was to drain just the top part of the loop (gpu/cpu blocks mainly) for adjustments.

i took into consideration that the drain port didn't restrict the flow; especially since the ball valve (switches the port on/off) has a very small diameter.
i have the pump off when i drain... nothing on (electrically).
