I appreciate your effort, [NAME] . I also kept searching for the part number, but to no avail. I ended up getting in touch with Dell Tech Support who gave me the following part number: DPXPF. The only way to order it is with Dell Tech Support as the part is not available on their parts locator web page as of yet. Through a few more Google searches I was able to confirm that the part number seems to correspond to the part I am looking for: Assembly,Holder,Peripheral Component Interconnect Express,W/RBR,3630. The moral of the story is that if you intend to get a GPU, you'd better get it when you order the PC and not wait for later 
Dear Community, Could you help me find the Dell part number of the PCIe card holder for the NVIDIA Quadro RTX 4000 GPU for Precision 3640? I ordered the GPU separately from the PC, but after I installed it I noticed that the PCIe card holder bracket was unavailable in the shipping box. The PCIe card holder looks like this: [IMAGE] The image above is from step 8 of the Remove the graphics card manual (in German). I was also able to find a real-life image of the PCIe card holder from a YouTube video (pause at 5:28): [IMAGE] Thank you!
