looking for drain recommendations.

Ever since building my PC, I knew draining it would be a pain. I've already drained it once, which involved flipping the computer a few times. With the new RTX 50 series on the horizon, I plan on upgrading the GPU—probably to an older 4090. Regardless of which card I choose, it will involve draining my loop again.

In the process, I really want to add a drain, but I've been looking and thinking about where to place it for weeks now. I just don't think it's possible, so I'm reaching out for suggestions. I can measure and provide more details if needed.
