A big shoutout to Liam, the whole process was uncomplicated and fast.

Speaking of fast, the PCBs arrived within ten days, and production finished in 5 days without counting the Moon Festival.

I even received more than ordered, a total of 10. The color is a bit darker then the previous revision by JLCPCB, but it's very subtle.

The edge routing is clean and the specified thickness is spot on and fits the PCI-E slot as intended.

From a quality standpoint, I cannot complain. Even the silkscreen torture test came in legible. Each letter is 0.5x0.5mm², following is a microscope shot.

The classic text to put under a chip, perfectly readable especially at a distance.

The solder mask itself is without flaw: it is crisp and pads line up perfectly. This prototype went all out with the surface finish by using immersion gold, which looks nice and is guaranteed to last long.

All in all, I'm very happy about the quality of the PCBs and how fast they arrived. PCBWay is definitely recommended.
