I bought this riser to be able to use the pci E port condemned under the radiator of my graphics card (nvidia card occupying 2 slots)
The riser just goes through, it's in contact with the CG heatsink but I was able to do the assembly without any problem, and thus recover the pciE port in order to put a wifi daughter card.
The riser head can't be fixed to the pc chassis...
I'm not sure if this is a good idea or not, but I'm sure it's a good idea.
