After testing my PC to prepare it for VR, I found that I needed an enclosure to mount my graphics card vertically so I could fit the required USB-C card into my 1x slot could insert. My only PCIe 1x connector is under my graphics card. Since all the images of the vertically mounted graphics cards in this 275R case didn't include the vertical graphics card cable, I was forced to share the build with its setup. This is the 16x PCIe dongle I used and it barely fits: https://www.amazon.com/gp/product/B06Y5YNGDJ/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 My motherboard doesn't have 4x PCIe ports , so Type 3.0 C was what I was limited to as opposed to 3.1+. For some reason, USB 3.0 Type-A cards don't work with Microsoft's VR Ready requirements. Although the card I bought has USB Type A, I haven't tried USB Type A on an add-in card. This can help determine if it's a Type-C or just an add-on card's chipset or something. Let me know if testing helps you. I borrowed a VR headset to prepare for purchase, so trying it out will take some work. Here is the PCIe 1x card I bought.
