Here are the expansion slots. I believe the first one is occupied by the
video card.
Slot Description
-------------------
1 PCIe 3.0/2.0x16_1 slot
2 PCIe 2.0 x1_1 slot
3 PCIe 2.0 x1_2 slot
4 PCIe 3.0/2.0 x16_2 slot
5 PCIe 2.0 x1_3 slot
6 PCIe 2.0 x16_3 slot
Which slot would be most appropriate for a serial port expansion card?
*If* you were to do this, one of the lowest bandwidth slots would be the
one to use. That would be any of the three PCIe 2.0 x1 slots.
That said, if you really have square pins on the motherboard for a
serial port, that's the best choice. Free Geek might have the
appropriate ribbon cable to DB9 with backplate. If not, I may have what
you need. Beware, though, that there are two common pinouts. You
should confirm that the square pins are present and what the pinout is.
