How da heck do I drain this loop?

[Beepes]

I got a little problem with draining my liquid cooled pc. I've more or less recreated the gaming pc side from this Linus video: 

Now since this build uses the EKWB EK-Quantum Reflection Uni 140 D5 PWM D-RGB Pump (shown below), my drainage point would be at the bottom of said pump with no space for a basin or something to catch all the liquid. I'm not very knowledgeable with things like these so I would really appreciate if anyone had any ideas on how to solve this.

Drain point doesnt have to be on the pump, you could use something else like a GPU port or add a 3 way fitting where you can place a drain valve.

Adding to that: If you want it to be even easier, attach a piece of flexible tubing to the valve that is long enough to allow you more control over the exiting liquid. It is better if it's permanently arches so you don't damage your loop putting it on and taking it off.
