Here's a teaser. I've done just about as much as I can for the moment.
I could tidy it up a bit and make some bits more pretty.
If I recall correctly this is the top and bottom layers with solder paste.
The middle layers aren't shown. Note that data signals will be on a middle layer.
And I'm still playing with the connector area. I may put pads for an SMD barrel jack at board edge next to PCIe power so that those who want no thru holes (due to heat sink) can use that. I could find no SMD mount PCIe connectors so best bet there is to drill the heat sink or put copper pads between it and the board. Kind of a nuisance really.
I should have changed the name of that silly 1PIN hole footprint.
