LimeSDR XTRX PCIe Adapter Board

I’ve located an industrial mini-pc with fan and both mPCIe and a PCIe(x4) slot which I hope to order and assess as a platform before I receive an XTRX. I am a bit (although not greatly) concerned about the thickness of the XTRX mounted on the adaptor card. I hope that I can obtain this information prior to ordering this PC. In parallel, I am trying to get a photo or drawing of the PCIe slot from the PC manufacturer.
