PCIe-4 riser cable re-creasing in meshlicious case

I have recently purchased a 'SSUPD Meshlicious' case. This case comes with a PCIe-4 riser cable that is pre creased to a 90 degree angle in order to fit the orintation of the compononts. The case supports variable GPU heights. I have raised the GPU to the heighest slot available.

I then shortly noticed that the riser mounting had to be adjusted which then causes the cable to unfold from its original 90 degree crease. This would require uncreasing and re-creasing another part of the cable in order to lay flat again.

I'm slightly adverse to uncreasing and re-creasing to adjust the shaping for the new cable height, based on riser cables in general feeling quite fragile. My last case the 'Loque Ghost S1' has a gentle curl in the cable, which seemed fine to manage. I'm a little worried that bending multiple creases back and forward in a expensive £50 cable could cause damage to the internals.

How has anyone else managed to neaten their riser cable for this case?
 
Probably safer to go for the original GPU position and get a right angled DisplayPort cable.

I got my case on order with OC UK, so helpful information for any owner.

Aren't PCIe riser cables similar to any other ribbon cables? I don't ever remember IDE cables being an issue with multiple bends?

PCIe cables are not tough, individually insulated ribbon cables like 1980s ones I don't think. They're more flat like mylar ribbon cables. They're notoriously fragile and prone to interference or damage.

Yes, just because they look a bit similar to IDE cables doesn't mean they are anything like them. Not even the fanciest UDMA133 cable with doubled up wires (AFAIR they had 80 wires for a 40 wire connection) were anything like these.

Even PCIe 3.0 ones are delicate enough.

But if a speculation this, but while PCIe is a super fast serial protocol those cables are not like parallel cable. Whereas all the high bandwidth serial cables (USB 3.0, USB C, Displayport, HDMI, etc.) use twisted cables or differential signalling to keep noise down, while AFAIK PCIe doesn't.

EDIT: take that last bit back, a quick Google send to imply PCIe does use differential signalling. And probably a while lot of other techniques to keep noise and interference down.
 
Big old bump here - does anyone have any further info or guidance on this?

I picked up a Meshlicious case yesterday with a PCI-E 3.0 riser, I have so far been unable to get a display output from the system I'm putting in:

Gigabyte B610i
i5 12600KF
RX 6600XT

After much testing and ruling out of the various components I narrowed it down to the riser cable - I set the mobo up with the GPU (PCI-E 4.0) directly inserted into the PCI-E 4.0 slot, this booted into BIOS fine. I then forced the mobo to run at PCI-E 3.0 and rebooted. No Issue.

Then swapped the components into the ITX case with PCI-E 3.0 riser installed, no output.

Have read various threads regarding AMD GPU headroom on the RX 5XXX series but nothing on RX 6XXX series GPU's being an issue.

Either way I have ordered a double reverse PCI-E 4.0 riser to try that but I am more than nervous about making the 90 degree fold in the ribbon so was curious if anyone has successfully done this, or has any insight as to whether or not I am just wasting my time and the RX6600XT simply wont work with a riser cable...?

TIA
