Thank you for that, must be blind because I could not find quantities for the video cables anywhere.It’s on the website.
the PCIe Riser, two low-profile DisplayPort 1.4 extensions and an HDMI 2.0 extension
currently there is no way to buy replacement/additional cables that Michael has told us about, they seem quite niche
In regards to buying more, I did find this: https://www.aliexpress.com/item/4000723029918.html
A2-A4T looks like it could be a candidate. For the cost seems worth a try. They offer DP versions as well.
