Clean looking way to add more USB slots to a case

“ The added USB slots are very useful and the board plugged right into one of the unused PCIE slots on my motherboard. ”

Works fine, but I wasn't sent SYBA brand.

“ My reads seem fine but my writes seem a bit low compared to my NVMe drive in my MB, that could just be my new cheap drive I put in, or maybe the PCIe slot I used though. ”
