I'll list my slots I have,
Slot 1 - Sound card, and I believe it's a x8, and the connector is colored black
Slot 2 - Graphics card, X16 and it's black
Slot 3 - Wireless card, X4 I believe, and it's black
Slot 4 - X16, but it's white, and i'm not sure what this means o.o
After Slot 4 is the edge of my case. The motherboard is kind of tightly fit in there. my mobo and case are in my first post too.
And I would just use a huge cable to connect to the router, but the router is on the other side of the house and down a floor
