The board he linked does not have a PCI slot, possibly because it is the PRO version. Its best to double check.
The difference between PCI and PCIex16 is that the key(or notch) for the PCI is closer to the edge of the board. This way you don't accidentally put one in the wrong slot.
Yeah pretty sure they left out the PCI cause it is a micro atx board. The full size has one. Thanks for the help.
I was mainly confused by this line in the description
1 x PCIe 2.0 x16 slot (black, max.@x4 mode, compatible with PCIe x 1 and x4 devices)
since I didn't know if the PCIe x 1 was different than a regular PCI slot.
