This is a really stupid question, but I just can't think of the answer, so I'm making this thread. What do you call the internal usb 3.0 headers? What search terms would I use to find a PCI card with those headers? I'm trying to find a 5.25" card reader for my desktop (never thought I'd need one, but since building it I've found myself working with micro SD cards quite a bit). Most of the ones I see for sale also have USB 3.0 ports built in, and besides that my 2.5"/3.5" combo hard drive enclosure has a couple USB 3.0 ports that I'm not using. I'd rather not have all of these USB ports on my computer that aren't hooked up, so I'm trying to find a PCI card (PCI-E x1 if need be, but I'd rather do regular PCI if possible) that I could hook up two sets of USB 3.0 headers too.

Thank you in advance, I know /g/ isn't my personal tech support, but I didn't know where else to go.
