I ordered custom sized PCIe power cables from DreambigbyRayMOD who is on ETSY. The cables to my RTX-3070 were 750mm long and I only needed 1/5th of that (150mm). Cables arrived in less than two weeks and work perfect. Also ordered 180 degree adapters to allow the cables to run toward the back of the system to the PSU. You can see the new cables on the two pictures on the right (blue cables). Much cleaner looking system.
