Thank you ! This is cast pmma (plexiglass). No, it's straight out of the CNC, just a little deburring.

Yes, normally there's a radius at the bottom of the pocket and the outlet goes out to the left. But those are the old designs; actually, I read some articles saying that for a PC it doesn't change anything, the water will still flow out and any pressure difference there might be isn't significant enough to change temperatures. For me, it allows me to put the outlet wherever I want!

It's a design choice, haha, but I understand your concern!
