LINKUP PCIE 5.0 Riser Cable | for Vertical GPU Mount | ITX Double Reverse | Graphics Card GPU Ready | Usable with PCIe 4.0 & RX 9070/ RTX5090 | 20cm (Total Length: 22.2cm)

I ordered this one works great. Get the 20cm version. https://a.co/d/0h4nYksy

Linkup 19cm double reverse V3, is a tight, perfect fit for 3 slot mode. Get 20cm if you want to put the riser on the 20mm standoffs, for two slot mode (20mm standoffs are included with the case).https://www.amazon.com/dp/B0DPVNKH42
